I've got an older pal that still has a reddit atheist streak but strictly with religion. Otherwise he's been reading Lenin and stuff, it's just something that really sticks in his craw. I'm not aligned but have put some effort into getting where people are coming from if they do have any of the larger religious beliefs. I'm a general lay off the religious guys and maybe appeal to their faith if possible. But for some it's just kind of a thing that is really hard to be chill about for myriad reasons.
