If you have it in for Christians, that's your right. But is this event really the best way for you to illustrate that? I would say no, it's not.
And attempting to link dropping two nuclear bombs on Japan to end WWII with some made up delusion about what Christians would do to the "Entire Muslim World" is about as weak and feckless as it gets.
You have plenty of valid, more applicable material to use, so why jump through hoops with this approach?
