I have no problem with rhetoric. I just detest those that take actions which may be reprehensible, and then use it to paint a wide group. People who say that soldiers love killing brown people because of a few stupid soldiers. People who say that America is evil, without thinking of all the good we do, etc etc.
I personally think the usage of nukes during WWII was unjustified and unethical due to the high amount of civilian casualities it caused. However, I don't think deciding to do so was "evil". There were valid reasons pro and con on that decision. I don't think the Founding Fathers were racist because they kept slaves... it was a totally different mindset back then, and I judge them according to the morals at the time.
There are only a few people in history that were nearly all evil... Caligula, Hitler, and a few others.
That's why I said I'm fine with people disliking aspects and working to change those. Totally cool. I just hate people who say that our country is evil, government is evil, yadda yadda yadda. If you feel that strongly about such a broad portion of the country, one that is essentially "unfixable", then either work to change it or leave.
I found that many of the peope with these simplistic thoughts also were not likely to try fixing it. But that's just my personal experience.
