I'm not religious myself, but as I've grown I've also had to learn, ironically, that I'm not a god either - I'm not all-knowning about other people, about their beliefs, about their lives and experiences and needs. In fact, I'm very mortal; I know very little. I couldn't dismiss other people's beliefs as lies, but I see them as something beyond me, which I haven't yet grown to an understanding of. In the case of religion, I've come to understand it a little and some things it provides, things that human beings need. If I someday become religious, it won't be because of a lie.
I would hate to be religious on Hacker News and see my beliefs - maybe very important and personal to me, maybe the core my family and community - scorned and dismissed out of hand. In that respect, HN is not a place of wisdom, intellect, and learning.
