The dawn of civilization

That has nothing to do with what I asked.

I already answered your original question.  I used to belong to an atheist forum about 15 years ago, and we would discuss science.  Most people were friendly, and it was more about looking at scientific research and using that as a basis for making assertions about things or even coming up with new questions for discussion.  Why not put up a banner if you only want atheists here?  As far as I could tell, it was an open forum.  It's also good to understand that many people do see this as a religious forum, even if you don't believe you're religious.  You could go to a Christian or Muslim forum, and plenty of people there would tell you they're not religious.  Also, a lot of the subject matter is identical.  Atheists talk about religion, if not more, than theists.  It may be with a negative outlook, but regardless, it gets lumped together especially on the Internet.

It appears you are unhappy with your experience here.  This isn't Hotel California...you are free to leave.

The fact that the forum isn't like the other forums you mention is precisely why there are multiple forums on most topics.

Suck it up Buttercup and stop telling atheists what they think.  Talking about religion does not make one religious any more than talking about music makes one a musician.
