If you were an atheist back in ye olde days you were executed. Unless you had power.
Okay, I didn't know that. Touche.
When Philosophy and Science were one thing. Christianity imprisoned Galileo for the rest of his natural life because he disagreed that the earth wasn't flat and most of the bibles physics. That's pretty unforgivable if you ask me.
I agree that what they did to Galileo and many others was unforgivable, but I think what KKK did as a whole is worse.
If 80% of America were apart of the KKK, would you think the general public would frown?(of America)
What are you saying? If you're saying Christianity is not frowned upon because the majority agrees with it, you're wrong. But I'm probably misunderstanding you, so I'm not going to dive too far into that subject. If you're saying that freedom of expressing faith is not frowned against because the majority agrees with it, that's a pretty bad comparison.
Hitler was an atheist believe it or not.
He wasn't against non-believers. He was against Jews. And anyone else who didn't follow him.
I feel that a better comparison would be comparing the relationship between democrats and republicans.
