Christians, you're still not giving me an answer to my question...?

Read the bio and history of the church of Corinth, then you will understand that when Paul said "let your women keep silent in the church..." he didn't mean that women should not preach. In fact, the word preach means to proclaim the good news or the Gospel. Jesus told all His disciples, male and female to proclaim the Gospel. About slaves, the Bible does not condone it but what the authors of the Bible are saying is that slaves should respect their masters even though they might not like slavery. It's the Christian way - you turn the other cheek. And please don't cherry pick the Bible. It also says that masters should respect their servants.
