There were people who were more cool with me being pagan than being atheist, down to one whose response was "No, you're not."

"Buh?"

"You're not atheist. You can't be sure, so you're agnostic."

I have absolutely no idea why it is so threatening to some people for others to opt out of the religious system. But she absolutely flipped out and decreed that it was NOT POSSIBLE for me to be an atheist.
