Like, how that ever became OK is insane to me.
Nah, I just think that in the 21st century, people shouldn't invade a country, kill all their children, and steal all their land.
But instead it has turned into a word that is used to try to shut down any criticism. Things get labeled as such, schools and others have a zero acceptance policy and here we are.
I have never seen a school having an "un-patriotic" policy. I would say even the opposite, they encourage getting involved in the government and making your voice heard.
I can say and criticize a lot of crap about my government without worrying about being kicked out of school or anything like that. The most I may be called is "unpatriotic" but I think most people here (maybe at least until recently) recognized that that was one of our core freedoms.
The same is not true if I tried to criticize one foreign government in particular.
