Why does America suck so much?

I just had a friend come back from the states and he kept on going about how fat and ignorant they are. He also mentioned about there being a lot of religious zealots.

The puritans didn't kill the native americans, they traded with them and unknowingly passed on their infectious diseases. I fail to see how instances of settlers taking land is any worse than the Mexicans taking land, I think the mexicans should be made to pay for their crimes, we should send back all of the criminals they put on american soil to save space in their prisons.
