"Just to sodomize his goats? That would do nothing to stop Islam."
What do you mean JUST? is this common place to you?

plus, i like goats. and who wants to "stop" islam? lol
by the way, i asked you to answer my questions as a muslim/christian/theist.
As a Muslim, no. I would not let this guy travel in time to sodomize Mohammad's goats.
As a Christian, I would also not allow a man to go back in time to sodomize Mohammed's goats.
Also, as a Christian, I would have an ethical problem with time travel.
As an atheist ex-Muslim, I would want him to go back into time and warn Mohammed not to believe his voices....and tell Kadijah to stop encouraging him. If neither worked, then I would instruct that he shoot Mohammad.
Then again, out of that, a worse than Mohammad could come....so I'd have to rethink it, even as an atheist.
