So I've been thinking about something today, and thought I would seek some American opinions.

Why is it that the people who seem to yell "AMERICA! FUCK YEAH!" the loudest, also seem to be the ones who think your country is so frail that the President could singlehandedly turn it into a dictatorship, and the only way to stop him is to amass a lot of guns? If your country is the greatest thing ever, shouldn't its system of checks and balances prevent this?

Just bewildered here. If it's so great, shouldn't they have a bit more trust in it?
