Title says most of it.

I'm curious about the UU church. What is it like? Do they require financial contributions? I'd be willing to give sometimes since it's likely how the church survives, but I can't do 10% of my income like I did as an Adventist.

I miss the community of the church. I can't really hang out with my old friends without hearing all about end times bull crap and Ellen White this and Ellen White that.

I do not want to be a part of another Christian church. I'm an atheist now, religion in general seems toxic to me. But the UU church does interest me. Those who have experienced it, what can you tell me about it? Would it be a good fit for an atheist or would the church of Satan be a better option?
