This is going to be hard. I want to tell you about a highly original, marvelously acted, adventurous piece of musical theater I saw on Broadway last weekend, but I don’t want to give away much of the plot. I would hope you would see the play, as I did, knowing almost nothing about the details except that it has the highest number of Tony nominations this year with 12, alongside “An American in Paris,” and concurrently has garnered spectacular raves from critics and audiences.

For a play to be so applauded, it would have to be creative and break new ground for narrative, music and staging. “Fun Home” does all that. Performed at the Circle in the Square Theatre on 50th Street just off Eighth Avenue, and billed as a family tragicomedy, the show is adapted by Lisa Kron and Jeanine Tesori from Alison Bechdel’s graphic novel, based on a memoir she kept through the years of her growing up.

OK, I will tell you it is both a coming of age and a coming out story. If you are the least bit uncomfortable with either of the themes, you should not see the play because the events portrayed are sometimes raw. And they are raw because they are heartbreakingly honest.

We all try to understand our parents, even more so as we age, because these are the two people who made us. In understanding them, we come to better know ourselves. So I will tell you further that the narrator of the play is the daughter and she is chasing her memories, trying to understand and come to terms with her father.

Memories have an evanescent, shimmering quality to them and that makes them hard to pin down with certainty, even in our minds, much less on a stage. Therefore the device that this play employs is particularly interesting. There are three actresses who play Alison, the narrator, at different times of her life — as an 8-year-old, a 19-year-old and her current age of 43 — as she looks on and occasionally cringes at what the other two say and do, If you think about it, we all react that way sometimes when we think of our younger selves.

So in this universal yearning to know our parents, some of the particulars of this family are unusual and in the viewing, they are wrenching. As has been said before, all happy families are happy in the same way, but unhappy families are unhappy uniquely.

Bruce, the father of three bright and imaginative children, is a high school English teacher, a restorer of old houses, the proprietor of a funeral home in a small Pennsylvania town and the husband of Helen, Alison’s mother. But his life is more than that, as divided personally as it is professionally, and therein lays the rest of the plot which I really am not going to tell you, however hard this is. I don’t want to ruin the surprises.

I will share with you, however, that the staging cleverly involves trapdoors opening and closing to disgorge and swallow up at different times objects in the home as large as the grand piano. When the lighting dims, it serves as a curtain would between scenes in a more conventional theater. And the music, highly original and opera-like as it is occasionally spoken and sung, perfectly carries forward the storyline and fills in the unsaid.

It is sometimes made up of big, brassy show tunes and sometimes of heartfelt yearnings.

Michael Cerveris and Judy Kuhn head up the cast in this poignant, provocative and haunting human drama, made all the more soulful because it is a real family we are watching. As they sometimes say on movie screens when the film ends, this story is based on actual events.

This musical play has gone in a new direction and can be as forthright because of the times in which we live.

Taboos can be spoken of out loud, and secrets can be revealed both on stage and in real life in an unprecedented way. This is both cathartic and liberating for audiences, as great art always is.

A recent editorial in The New York Times decried a blatant act of anti-Semitism in Europe. Fans in a major soccer stadium in Holland chanted “Hamas, Hamas, Jews to the gas,” and “Jews burn the best.” The home team, FC Utrecht, subsequently apologized for the outrage that occurred in a game against Ajax Amsterdam on April 5, but just imagine how someone Jewish in the stands might feel in the midst of those shocking outcries.

Worse, it was not an isolated incident. Kick It Out, a British watchdog organization, has reported that there were 59 instances of anti-Semitic slurs in the first half of the English Premier League soccer season, with chants of “Yids” and “Kill the Jews” at games.

According to the Simon Wiesenthal Center, a human rights organization, there seems to be a new alliance between neo-Nazis and jihadists. After the terrible consequences of anti-Semitism in Europe in the previous century, it is hard to believe such bigotry still exists, much less is alive and flourishing for the rest of the world to witness.

What is anti-Semitism today and how did it start?

According to columnist David Brooks, there are three strains of anti-Semitism circulating now. The first is in the Middle East, where it feels like “a deranged theoretical system for making sense of a world gone astray,” according to Brooks. Iran’s supreme leader, Ayatollah Ali Khamenei, calls Israel the “sinister, unclean rabid dog of the region,” whose leaders “look like beasts and cannot be called human.” Iran’s President Hassan Rouhani “reinstated a conference of Holocaust deniers and anti-Semitic conspiracy theorists,” who propagate the usual conspiracist idiocy about Jews drinking the blood of non-Jews and spraying pesticides across arable lands.

“This sort of anti-Semitism thrives where there aren’t that many Jews,” according to Brooks. “The Jew is not a person but an idea, a unique carrier of transcendent evil: a pollution, a stain, a dark force responsible for the failures of others, the unconscious shame and primeval urges they feel in themselves, and everything that needs explaining. This is a … flight from reality even in otherwise sophisticated people.”

Incredibly it can be a part of the architecture of society and taught repeatedly in some madrassas or schools to children. “It cannot be reasoned away,” said Brooks, “because it doesn’t exist on the level of reason.”

“In Europe,” Brooks continued, “anti-Semitism looks like a response to alienation. It’s particularly high where unemployment is rampant. … The plague of violence is fueled by young Islamic men with no respect and no place to go.” Brooks goes on to say that thousands of Jews a year are fleeing Europe. The echoes of terrors throughout past centuries are nipping at their heels.

In the United States, which Brooks pronounced “an astonishingly non-anti-Semitic place,” nonetheless there is rising tide of anti-Semitism, especially on college campuses, with its basis seemingly in Israel’s policies toward Palestinians in Gaza and the West Bank. But why the policies of Israel should reflect on Jews in America any more than policies in Ireland reflected on the Irish in Boston, or the discriminatory and shameful treatment of Japanese Americans interned during World War II should have ensued, is simply bigotry. And anti-Semitism is a particularly virulent form of bigotry whose dark underside is hatred leading to violence and even extinction.

History is filled with brutal examples including the pogroms, which preceded the First Crusade in 1096; the expulsion from England in 1290; the persecutions of the Spanish Inquisition and expulsion from Spain in 1492; the Cossack massacres in Ukraine, 1648-57; the pogroms in Imperial Russia between 1821-1906; the Dreyfus affair in France, 1894-1906; and the more recent horrors of the 20th century, just for a historical overview. It’s an evil virus that sometimes hides but does not die.

Brooks suggested that the best response is confrontation, arousing the “brave and decent people” to take “a page from Gandhi” and stage demonstrations, as laws and governments reign in even the smallest assaults.

“Disturb the consciences of the good people. … Confrontational nonviolence is the historically proven method to isolate and delegitimize social evil.” Is that enough?

We seem to have conquered or, at least, mitigated the virus causing AIDS. Perhaps against this form of racism, we can together do the same?
