flipnflap - just want to try something with what you wrote:
You wrote: The key to Islam is brainwashing. Children born in certain countries and communities automatically become Muslims. They have no choice and, if they wish to leave, their punishment isn't worth thinking about. Anyway, their education is so Muslim-slanted, that they rarely think for themselves.
Just going to substitute a couple of words:
The key to Christianity is brainwashing. Children born in certain countries and communities automatically become Christians. They have no choice and, if they wish to leave, their punishment isn't worth thinking about. Anyway, their education is so Christian-slanted, that they rarely think for themselves.
Your point may be valid but it applies to every religion not just islam.
