Yes. I'd argue Judaism and Islam aren't religions in the traditional sense. They are religions, but not in the way Christianity is. If you're a Jew or a Muslim, you're looked upon differently here in the US (generally speaking). Every Jew I have ever met identifies as Jewish, not White, and most of them are of very pale complexion. Muslims are often thought of as another ethnicity where I come from especially by older folks as a catch-all for Arabs.
Yeah. Last week a buddy of mine who is a practicing pale face christian explained that he is jewish under jewish law because his mother was jewish and will therefore always be jewish even though he has never personally identified as Jewish or believed in their religion. Sounds like a totally legit way to identify groups.
I'm speaking simply from personal experience. Jews I've met don't identify as white, even if they are. Islam has the same sort of thing going on, but that's because we've made Muslims feel like "the other", to the extent that it's enforced their group social mentality.
