Having lived in America for a few years, and been going there to visit family often otherwise, I have a different perspective to offer than the other comments: I don't have to be proud of the government to have deep respect and admiration for the people I've met.
America is a big place. I've been to around 38 or 39 States, most passing through, though the one thing that stood out is the perseverance of the people.
I think you all should be proud in your general strive for not accepting things that are obviously wrong to you. There are disagreements, but at least you guys legitimately make effort to make things right as you feel things should be.
There's uproar in the streets, yet it's evidence that people do not want to just sit around and do nothing. I've witnessed sincerely compassionate acts of kindness, in ways I'll never forget. I was homeless for a short while, in Arkansas, and there were people so fed up with the lack of government support, that they themselves just bought apartments, and converted them into soup kitchens where they could feed us. One man had a felony, he spent time in prison for being involved in someone else's demise, yet he did this and spoke his story, not to boast in any way but to hopefully inspire many of us to turn our lives around.
It's a shame the government situation is a bit muddled, although it is also a bit of a mess in the UK, though I just think you guys should be proud to be American in some ways, even if your government is trying to convince you otherwise with their dishonest policies.
