That is not really a viable argument, especially as the Christian church has been responsible for far worse.
That I can't comment upon. I do, however, agree that the foundings of the Islamic religion are just as shaky as that of the Christian and that the actions of it's founders are just as morally impeachable.
I'm trying to figure out where this is going. What do these statements about a Christian church have to do with the rightness, wrongness, or otherwise of the 8-year old being married/sold off despite the protest of both the child and the mother?
