The USA died during the McCarthy Era, when patriotism somehow became about loving God and your government instead of being loyal to your country and fellow citizens, even if that meant going against the government. That lead to a new breed of hypocrites who claim to love the flag and the constitution, but refuse to hold up the ideals -- civil rights, freedom of speech and expression, the right to due process, etc. -- upon which those things were based. Patriotism is now all about worshiping symbols instead of upholding what they're meant to represent... and you fail to see how that renders those symbols meaningless.
I may be a Canadian, but I happen to admire many of the ideals upon which the US was founded. It's just too bad that people like you feel the need to destroy the work your founded fathers did to ensure those ideals were upheld.
