Josef Stalin, Vladimir Lenin, Mao ZeDong, Kim Jong Il, enough said.
Wake up, people! Every group in existence has bloody history. Christians have the crusades, Muslims have today, Atheists have Asia, Jews have the time in the Roman Empire, and so on! Come on, people!
Do you know why these monsters use Christianity, or atheism, or what have you, to do what they do? Because that is their shield! Their cover. What authority would the pope in the middle ages have if he didn't brainwash the people under some fallacy that he was God's representative?
Atheists can be good people. Christians can be bad people. That's the reality. Can't we all just get along? Clowns like those examples come to power when people forget that I, a Christian, have blood just as red as an atheist's, or a Jew's, or a Muslim's.
You have been educated. Keep the applause to yourself.
