"If the our government sanctioned slavery I would say it was wrong because it would be against our Constitution."
Too late, you have already said you don't think slavery is wrong.
""My position on slavery? I don't consider it is wrong to have slaves. "
And what if the Constitution was amended to include slavery? Would you have any kind of moral argument against it then?
"What is right or wrong for one country is not necessarily right or wrong for another country. Just ask the people living in other countries."
So you are a moral relativist?
Like I said, the Bible doesn't support it nor does it condemn it, so who am I to say it is immoral.
