If only!!! A good second best would be to get them to actually follow the example of Jesus/Mohammed... In this very thread you have Christians advocating for things that the Jesus they claim to follow would be appalled by and being world class a-holes while they're at it. Crazy.What we need to do is convince the radicals of Islam, Christianity, and any other religion, that there is no afterlife. Because there is NONE. So there is no point in doing all of this. The wool has been pulled over their eyes by centuries of asstastic deceit and guile by people who wished to control the populations for their own gain.
Sorry dude, there is no afterlife. When you die, THAT IS IT. So stop killing innocent people for the name of a deity that DOES NOT EXIST! Just chill out man.
