Her dad is Jewish, mom isn't, and parents are divorced. The extent of her religion is "we said the prayers on hannukkah." Last night she heard about some right wingers she's barely related to say that Jewish people go to hell. This then led to my gf saying that "the left" also does the same thing.
Is this what the kids are calling "the ick"?
Have you tried radicalizing her? It... Well it might be a little late, but the whole 'you are a human who deserves rights' thing might be appealing.
