Yeah, lest the Right try to think that the Left is the only one with a morality goal.
I like your rundown: it really did put words to something I have noticed. I am also just amazed about how many right wingers are about this site: are these the fabled dude bros of X-Box Live?
Anyway in my own view both too much Political or Patriotic Correctness is dangerous, but I feel that the latter is the most likely to cause trouble.
Too much Pol.C could, theoretically, cause us to overlook something out of a desire to not be offensive, too much Pat.C is going to cause people to not question something wrong.
I have no sympathy for the 'Just Following Orders' Excuse: if your patriotism causes you to do something wrong, you deserve to be punished.
And yes, the Confederate Flag hypocricsy is frankly obnoxious. Anyone who flies that thing around has no right to call anyone a traitor: or lest we forget who started the war that killed the most American lives.
Hint hint, it wasn't Al-Queida or Imperial Germany.
