He would have ignored it actually, im muslim but i didnt care about the stupid video. The prophet used to ignore nasty comments about islam.
it was muhammed who attacked caravans for money so I would say, no he wouldn't.
islam was brought by the sword so I believe muhammed would have no problem with fighting anyone who disagrees, actually killing non muslims is a basic islamic rule,
no he wont like people find out what he was
Yes, kind of like Christ has ignored all the stupid things we do. Besides I beleive in one god.
