Never call Sarah Silverman “un-Jewish”—or you’ll be sure to get a nasty response from her father.

Orthodox Rabbi Yaakov Rosenblatt recently published an open letter to the comedienne and activist, criticizing her lifestyle, to which dear ol’ dad responded harshly in his own letter.

“I think, Sarah, that marriage and childrearing are not in the cards for you because you can’t focus on building life when you spend your days and nights tearing it down,” he said in the criticism, citing that she focuses on her career over family—which is not-so-kosher according to the Orthodox belief.

“Nothing you say or stand for, Sarah, from your sickening sexual proposal to a Republican donor to your equally vulgar tweet to Mitt Romney, has the slightest thing to do with the most basic of tenets which Judaism has taught the world—that the monogamous relationship is the most meaningful one and that a happy marriage is the key to wholesomeness.”

While Sarah probably brushed the personal attack aside, her father Donald Silverman came to her defense, writing a response to the rabbi (as published by TMZ):

"Hey a**hole. 

Daughter #1 is a rabbi. Not by your standards. She's reform. How dare she, a lowly woman think god wants her to be a rabbi, created from a mere rib. Her hubby, three times nominated for a nobel peace prize was listed by the Jerusalem Post as the 49th most influential jew in the world built the worlds largest solar field in Israel.

By the way, Sarah was also on the list. I missed your name. Oldest granddaughter is serving in the Israel Defense Forces. I'm sure you also served. Oh I forgot the orthodox don't do that.

You don't f*ck with my family."

Sarah’s response?

“Oh, Dad! You’re my hero. Where do you get such moxie??”
