To those of us who believe in no God at all, you’re saying that your God is an asshole. You’re telling us that making everyone worship Him is more important to God than saving children’s lives.
To those who believe in different gods, or different ideas of the same God, you’re telling them that they are part of the problem because they want their children to go to school in a non-sectarian environment. You are asking them to think there would be less violence in the world if they allowed your religious traditions to be honored in the public sphere, at taxpayer expense, above their own.
If one is going to tell a lie, make it a big lie, tell it loudly and tell it often and eventually people will come to believe it. ~Josef Goebbels
