I agree with you, I was about to say the same point before reading your reply.
judaism is kind of an exclusive religion to jewish people, passed on to their own generations, and they want it that way. Even if you want to convert to judaism, you have to make required steps as if they want to make it hard for you! There are also cultural jews as you and April said, so those reasons together are the ones responsible for their (IMO)unintentional tolerance, it's more likely to be like you(Jarrod) said: "They are not particularly concerned with anyone else's beliefs."
My best friend 'disowned' me when I came out. That was in January of this year and it still makes me cry. I still have dreams about her now and then and feel like shit when I wake up and realize it wasn't real. I miss her, but I'm not going to go begging for her friendship. It's her choice and she's really being a SHINING example of Christianity. (lawl)
My mom thinks I'm lying and that I'll change later. That I'm just rebelling (wtf). She talks to me like atheism is a disease and I resent her for it. She's Christian.
My Christian grandparents pray for me in church every Sunday. (GREAAAT)
My dad is a deist and he accepts me even if he doesn't agree with me. I'm so grateful to him for keeping religion out of our parent-child relationship. It makes things a million times easier.
I know a few people online that are pagan, Buddhist, Muslim, Jewish, and all that other good stuff. I can only think of one that isn't accepting of me and my atheism. She's Muslim and she gives the fundie Christians a run for their money. I find the most accepting folks to be the pagans. I've never had one tell me I was wrong for being an atheist.
