You totally should have read BlueNinja's comment that I was replying to. Then I found out that BlueNinja is a Christian.
I made the assumption that he was just another atheist leftist ignorantly attacking Christianity.... again....
What I meant is that if any atheist should make baseless attacks on Christianity then I would just flip it around and base the holocaust of the 20th century on atheism.
"No, they didn't. They murdered people in the name of communism. Atheism isn't communism."
Not all atheists are communists but all true believers of communism are all atheists. Atheism is not communism, you are correct. But communism cannot fully function as long as there are theists running around. The prime directive of all ism's based on socialism is to eradicate religion so that the ism becomes the new religion and the gods are those running the government.
"Except there are things in the US Constitution which directly conflict with things in the Bible, like freedom of religion. The 10 Commandments prohibit freedom of religion, the US Constitution guarantees it for all American citizens."
Oh Octavia, Octavia, Octavia... what am I going to do with you? The 10 commandments does not prohibit freedom of religion. God is not a religion. Religions are created by those who worship God. That is why the God of the Old Testament is revered in Judaism, Christianity and Islam (although Islam's idea of Allah is a radical departure from the Jews and Christians).
Considering that our founding fathers were all devout Christians I tend to believe that they were very familiar with the 10 commandments. If they wanted to create a theocracy they could have but the found in the Bible that God will force no man to heaven and so they went with that approach and formed a secular nation where the individual was left to "work out [his/her] own salvation with fear and trembling" (Philippians 2:12)
Despite the fact that God issues commandments, those commandments have always been up to the individual to keep or disobey. It was NEVER the responsibility of the government.
"Like all the other animals that exterminated themselves just because they didn't have religion?"
Animals and humans are not the same. Animals lack the ability to reason.
