There is even an author who used the pen name P.A. Triot, but as he is writing about secession his pen name needs to be T.R. Aitor. It is also considerably ironic that people who call themselves patriots also call for secession. A real patriot works to change the country from the inside, not to just break away from it.
There is a lot of cognitive dissonance though, how often do you see a truck or car with an American flag on it right next to a Confederate Battle Flag? So, you support your country but, you are celebrating a time of deep division that nearly destroyed your country. People like that just don’t seem to use their thinking brains to well. Cognitive dissonance is what certain politicians want when they seek to divide and lure certain parts of the population away in order to win votes. So if you like being taken for a fool keep up with the cognitive dissonance.
It may seem extreme to say this but in Germany in the 1930’s they had a massive rise in Nationalism that look like some of what you can see going on in certain parties in the US. But we can be better than that, we can stop the hate and work together for all Americans. Learn from the people who are different share your culture, enrich yourselves. Love one another like the way you claim to love your country and that will make all the difference.
