1. Showing that you do the same thing is not changing the subject.
2. If you hold that, then it also does not represent Christianity in general. At least try to be consistent.
3. Do your own research. Read about atheism and the French Revolution. This would be enough to put a pin in your original meme.
4. You make a statement with no support. Prove or support your assertion. If you are right I will agree with you. There have been many evils done in the world, some of them by Christians, some of them by atheists.
5. It is the same level of faith. I know atheists hate that, but philosophically it so, because there's no absolute proof, not non-proof of God's existence. At least be honest.
6. Now, you've called me retarded and stupid. Maybe don't engage in an adult argument if you can't descend to name-calling.
