We should always have loyalty and allegiance to our nation. We don't have to support all it's actions, but you can't really hate on the idea of Nationalism. It's not creepy or wrong. Children should learn it, but not be forced to recite it... instead the nation and the adults in the nation should be creating an environment in which people would want to grow up and serve their nation.. and learn the pledge.
The part about God maybe shouldn't have been in there in the first place, but it's there and it's not killing anybody to have it in there. Don't say it if you don't want to or relocate to a nation built upon different principles.
