What difference does it make if an Atheist converts a Christian?

I don't go around trying to convert people, unlike most Christians. Atheist do not believe in the Anti-Christ, and our main goal is not to convert. Who was it again that killed hundreds of people if they did not convert....oh yea the Christians. It is not my life's mission to change people's minds, just to open up their thinking. I don't care if people believe what i believe, i could care less, i just do not like to have other people's beliefs pushed on me, so why would i do it to someone else.
