I already know what Aquinas's argument is.
Don't care. It's obvious that the social norms were different. I have more of a problem with God being in favor of the social norms.
So, what I am getting from you is that if one doesn't do something to stop the government from doing anything that they disagree with at all, that person is condoning the government's actions. You have stretched the meaning of the word "condone" so far that it has become meaningless.
No, I didn't. Your terrible reason comprehension strikes yet again. My position is that a good, all powerful god would not allow slavery, because he's good and all powerful.
This doesn't make any sense at all. My argument is that an all powerful, all good god wouldn't allow slavery. I'm not saying that that means that God therefore doesn't exist. You are just making up.
So? Just because laws can be change in theory doesn't mean that they will be changed in reality. And again, your position is illogical and impractical.

at an article that justifies the murder of children. And that still doesn't explain why non-believers deserve death.
No, it isn't.

thinking that dropping all ties and finding a country one agrees with completely is easier than dropping a religion. You are absolutely ridiculous.
You are saying that it is easier to leave one's job, family, community, attachments, property, etc to find a country whose policies that they agree with 100%, than it is to simply look at a religion's tenets and reject them. That's moronic. You said yourself that you CHOSE to believe in God. I never CHOSE to be an American. That completely destroys your weak argument.
Yes, God has commanded his followers to kill people. It is in the Bible. It expressly says to kill witches, false prophets, non-believers, pagans, unruly children, etc. You can read those passages so hard that you can come up with completely different interpretations, but that doesn't change what they say.
Yes, it is common knowledge that people will argue for the position that they agree with. I'm sorry that you are so ignorant to that obvious fact.
Yeah, you're for murder and I am not.
No, the existence of God is the conclusion that you are trying to arrive at.
Your argument is circular. You are saying that the evidence of God's existence is everything, which is silly. "God created everything because everything was created by God" is a circular argument.
It's atheism, too. You brought up agnosticism because you were under the mistaken belief that the two were mutually exclusive. Either that or you having typing Tourette's, which makes you post random things for no reason.
You claimed that the burden of proof is shifted when one makes the claim that God doesn't exist, and I said that nobody made that claim. I'm not going to take your burden of proof. Sorry, but you still haven't proven the existence of God.
