One thing you have to keep in mind when you decide to come out of the closet with your atheist views is that you cannot be affected by what other people think.
Even those who claim to be atheists may just be using the cloak of that title to gain some margin of authority over you, yes, just as the religious use that facade.
I am not an activist. My views are just that. Now, if I were to become dictator of the world, that could change I suppose. Total power is totally corrupting, you know.
