I am rare. I am quite vocal myself... I know many Atheist (we have secret meetings how to overthrow the world we are the Evil Atheist Conspiracy
)
but honestly most Atheist I know don't find it nesesary to subject themselves to the abuse that the masses put them through (I know I have gotten my share) and I don't blame them for not wanting to put up with that shit. They tend do things in a more passive manner.
