God and Jesus are the same Person. The Trinity is the Holy Ghost, God, and Jesus. They are different and yet the same: being humans, we cannot try to understand this. The Bible does not support slavery. Slavery is what sinful people do when they have strayed from God. God is pure, separate from humans, but Jesus is the bridge. Sin is why people act evil, or do evil things, and that is why we must believe in God to be saved.
Women are supposed to submit to their husbands, yes. But that doesn't mean it the way you think. It basically means that we should try and heed our husbands' words if he is a God-fearing man. We do not have to obey, but we should try and listen to them.
Also, take note that Jews have different views/traditions than modern Christians. And you are pointing out your own sins, not God's. Most of the things Jesus says are not against or racist/sexist etc. It's only the way YOU interpreted them.
Also, I agree with what Snickerdoodle and Kitten said. The Bible uses words that mean different things now. For example, "replenish" meant to fill, not refill, in old Hebrew. So, please read the whole Bible before discrediting it. When you don't thoroughly research your subject, it makes you seem a bit dumb. Believe me, it's happened to me with other things.
And, also, it's quite rude for you to try and offend so many people at once. Sure, you may not believe, but that doesn't mean you have the right to try and be like this. Thanks. One of the reasons I hate answering these questions is cuz of how ignorant some people choose to of the bigger picture of someone's religion. People need to be an expert in something before they decide to bash it.
Have a nice day
