I don't know what you are talking about. Human rights are pretty clear-cut. The fact that some racists kill people they don't like doesn't have anything to do with anything. That's not a right regardless of what they think.
You stated that the US is founded on fighting for your rights. You are correct in the sense that that is literally how the US was founded. The whole right to bare arms is based on being able to defend yourself against a government that has gone astray.
Now, my point is that the only time in US history people felt forced to "fight" for their right against a government that has gone in their eyes astray is during the civil war. Note that we are not dealing with "some racists" but rather a large group of people that felt their livelihood was taking away, mainly by prohibition.
The only other "peaceful" fight against the government came from MLK.
I think US citizens have been very non-critical with regards to their government. In 9 out of 10 western countries the Iraq lies would have led to a crisis most likely followed with the forced resignation of the government or re-elections, here it seemed of very little consequence.
I don't think most people in any western Country really knows what it means to fight for ones right, and if the US was ever founded on this principle it certainly is not anymore, and that is a sad conclusion.
