Sometimes you just have to pick your fights. We had guests over the first days of the chag (holiday) whose son, who had just returned from a year of study at a yeshiva in Medinat Yisrael, proceeded to quip, "my rebbe in yeshiva told me that the most depraved Jew is more righteous than the nicest goy (non-Jew)." I was infuriated but opted not to respond to a comment that, in the scheme of things, places Bernard Madoff on a higher spiritual level than say a Mother Theresa or the Dalai Lama.
My seder was ripe with jokes about Modern Orthodox rabbis (followed by jokes about Reform rabbis) along with a couple of jokes about Mexicans where someone explained to me that all Hispanics are Mexican. Can you say..."cruising for a bruising"?
What kind of trash talk did you hear at your seder? Go ahead, get it off your chest, I'm listening.
