The simplest definition of patriotism is a love for your country. One thing the right loves to do is paint liberals as anti-American, unpatriotic jerks. The unpatriotic liberal is now ingrained in many people's minds, so deeply that even the notion of mild patriotism seems absolutely terrible. Yes, we know how badly nationalism when unchecked by reality can turn out. But I don't think that patriotism is something worth fearing - moderation is key.
I'm proud to be an American citizen because despite the bad, which every country has its fair share of, we have a lot of good to offer. Our ability to unite cultures, the rights we enjoy and often take for granted. Our history, the creativity of our people. We're a pretty nifty bunch. We do have a lot to improve upon, but it takes a patriot to continue the work. I want to see my country do better because I love it, even if it is riddled with people who would despise me based on my political opinions alone.
Do you consider yourself a patriot of your country? How much patriotism is "enough?" How much is "too much?"
