Sarah Silverman's Dad -- UNLOADS on Rabbi Who Called Sarah Un-Jewish

Breaking News

Sarah Silverman's father is TEARING INTO an Orthodox rabbi who criticized his daughter's life choices ... calling the guy an a-hole ... and warning him -- "You don't f*ck with my family."

Papa Silverman is responding to an open letter published by Rabbi Yaakov Rosenblatt -- in which he goes after the comic for living an un-Jewish life -- which includes choosing her career over having a family.

Rosenblatt wrote -- "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 went on ... "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."

Now for the response -- Sarah's dad, Donald Silverman, issued the following letter back to the rabbi:

"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."
