I don't want to be an asshole and alienate people, but this question leaves me feeling like whoever is asking it has such a radically different (and crazy/unfounded) world view that I dont know how to even talk about it.

I've found "I do not identify with any astrological sign and dont welcome anyone ascribing one to me." Is not received well.

In some ways, it's similar to some people not identifying with a specific race or gender and dislike being assigned that kind of label by others... but it's also very different.

Imagine a Christian asking a Hindu, "what kind of Christian are you? What's your birthday?" And when when the hindu replies, "I'm not Christian at all, I'm Hindu, and my birthday is June 9" Then the Christian replies, "Oooh, so you're a Baptist! That TOTALLY makes sense!"

But seriously, what are some good atheist responses to this question that won't immediately alienate people? Something funny-yet-honest, ideally.
