The First Amendment contradicts the First Commandment.

Christians think they're oppressed when they're not allowed to oppress others.

Most reject the more repugnant or indefensible dogmas while still holding onto some core belief. Many believers will proudly describe themselves as "reasonable" or "rational" based on how little of their religion they still embrace versus how much they now reject. I think it's funny when people realize that the less you believe the more reasonable you are, but they stop before they reach the logical conclusion.

But the biggest problem with being fed lies about how great we are is that people won't be prepared for how evil this government has already been and therefore can be again.

That's what drives science though: trying to find out the way things are, the way they were, and the way it really works. If that is your goal, then you want to make sure that your information is accurate, and if it's not, then it doesn't matter how much you liked that old urban legend or fictional factoid you once bought into. You will discard it, and be embarrassed by it, seeking instead for truth.

No god worthy of worship would be associated with such character flaws as vanity, jealousy, vengeance, or wrath. God should be above such deadly sins and would not be encumbered by them.
