I think Unitarian Universalsm http://en.wikipedia.org/wiki/Unitarian_Universalism is some kind of organized atheism.

Ssh! Do not inflame the coffee-fueled wrath of the Unitarian Jihad!

Seriously, though... despite the fact that some UUs are indeed atheists, most of them (including many of the atheists) would disagree with this statement.

it is acceptable to be a UU and believe in God or not believe in God. That is why some people think UU is not a religion- it doesn't have dogma.

and if you don't think they're tolerant enough, there's always http://www.themonastery.org/

"I suspect, baldness itself will become an accepted hair color several decades from now".

See how silly that sounds? Atheism is not nor will it ever be a religion.

It's happened long ago: Communism. One of the central dogmates: "Religion is opium for the people" (Marx). It went all the way here in Russia: purposely desecrating churches, blowing them up, using them as warehouses, shitting on icons etc.; newspapers named "Atheist" or "Blasphemer"; killing priests en masse as "reactionary elements".
