What do Atheists, LGBT, and Women all have in common?

edit 1:

So there has been some negative response to this post. Let me make something clear: I am in no way equating the oppression that atheists get to those of LGBT and women, but rather I am stating the simple fact that atheist are oppressed. Simple as that.

From first hand experience, I have been on the receiving end of discrimination and oppression more as an atheist than as a member of the LGBT community. That is not to say that every person has experienced it in the same way, but that is the way I have experienced it.

Furthermore, for those who doubt that there is really any true oppression of atheists, let me leave you with a link to an article and a quote:

How dare you take what I say spin it into something it didn’t say and attack the your misconstrued version of it. I did not equate the level of oppression as being equal nor did I compare the levels of oppression, but to discount the fact that all three groups have been oppressed historically and currently makes you ignorant of the realities of world.
