There are Unitarian Universalist churches. I didn't like the vibe, but/because I think it works perfectly to what appears to be the target audience of people who cannot lie to themselves anymore about religion not being BS, but still want the social aspects of a church. But, it is a thing... people there are very kind in my experience. I though I was trying to be spiritual but the time I went was when I moved cities and was also pretty lonely for some time.
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.
There are much better ways to beat loneliness. This only creates problem not just to the individual but to the society. Less religion is better.
