All Jews are white or Eastern European. (And eat kugel and gefilte fish and cholent every Shabbat because otherwise, they wouldn’t REALLY be Jewish.)
Jews don’t welcome converts. (Is this a myth? Alright, in some communities it is. But in others, as we’ve seen in Israel and South America, it’s a fact. A sad, sad, sad reality.)
Rabbis are male. (Even secular Jews have a problem with this which I find very interesting.)
There are the myths that Sandy Sasso, a Reconstructionist rabbi, tries to debunk in “Debunking the myths of Judaism” but how much can one little article in The Indianapolis Star do? Well a lot if you send it to all your friends and their friends and then Facebook and Twitter about it!
