UH Slavery undoubtedly is, and their is passages that some believe are against IR. That's their opinion.
Did you write the bible? How do you know how accurate that bible is? And bottom line is everyone has their own right to their own religion. Everyone has the right to sin within their own religion. It is not your place to tell someone what they can and can not do when they are not victimizing people. It's a sin to have sexual relations without being married is it not? Are you promoting making that illegal or crime? Divorce is a sin. Remarriage is a state of living in sin. Are you promoting making that a crime or illegal? Or do you just pick and choose as it suits you?
Who is promoting anything???? I did not write the Bible, but as a Christian, I study it and learn from others who study and teach it. I merely defend what the Bible says and point to the truths in it. Do I like everything that's written in it? Heck no! Do I always obey everything to the letter? Again, no. If I could, I would have no reason for a Savior. But I do acknowledge sin, even when I'm the one sinning. I have faith in Jesus Christ, who is the word of God, incarnate. So if the Bible is inaccurate, then Jesus was a fake. I'm not gonna stand before God one day and tell him that. Will you?
