Now that I have several point of views, I'll venture then my take: This site has the construct/making/foundation to be an echo chamber for non-believers which I interpret to being a close community of like minded individuals that feel safe to belittle/dehumanize/victimize another segment of society. However, base on the comments and diverse point of views to date, I think it is more of a safe place to discuss openly and question some things that cannot be questionned outside rationally. Thanks all for your input!

Its whatever you want it to be.

As with anything else, I take what I want and leave the rest. ..

There are a few theists here that, like cockroaches, emerge from the cracks on a rather regular basis.

Are there sites or groups that encourage theist/non-theist discussions?

Look at the name of the site. Ponder that for about 10 seconds, then ask the question again. See what a difference that makes?

Yeah, is this site an echo chamber for non-believers? (Sorry, couldn't resist.)

Serious answer: I think it is necessarily an echo chamber to some degree, because it's a place for people who share a specific point of view. It doesn't mean that the site is monolithic, or that there aren't people here who disagree on various topics, but a site designated to be a community of agnostics and atheists is of course going to strongly reflect those topics.
