By your logic, the Old Testament has no place in Christianity because Christianity is named after Christ, who post-dates the Old Testament.

You are also ignoring the obvious fact that Christianity went through some bloody and repressive phases, but reformed itself. Why can't Islam do the same?

[OK]

Islam can't reform itself because Muhammad was not a holy man, whereas Jesus was. It is like trying to reform Charles Manson's cult.

Since I am not Christian, I can only speculate on your thesis. My understanding is that Jesus brought a new covenant of love and compassion to replace the old covenant of an eye for an eye etc.
