OK, here's the thing. I'm pretty sure that religion is not the root of *all* evil. But I am sure that if your imaginary friend is telling you to kill schoolchildren, you need to lose that imaginary friend. She/he/it is not doing you or the planet any good. Just lose them.
While we're on the subject, I might give the same advice if your imaginary friend(s) are telling you to hate homosexuals, Blacks, poor people, foreigners, or almost anybody. Except those whose imaginary friend tells them to kill schoolchildren. With them, you're on your own.
