Now that I read your post a bit more Typhoid, a lot of your assumptions are just based on not enough knowledge. For example why Jesus was following another religion than he ended up preaching. Before him, judaism was the true religion. They had a lot of prophecies about a messiah, so they knew something was going to change. That messiah turned out to be Jesus. Many jews accepted that, most did not.
If you knew a bit more about the bible, you would probably understand it better.
