That tradition hasn't died out yet. There are a ton of common sense things done in many European countries that aren't implemented in the US because of apparent links to "communism."
Could you give some examples? I am from a post communist country and am interested in what could be percieved as communist in the US. My guesses are publi transport and universal health care on the top 2 spots.
Depends how deep into the south you go. It fares from clear ones, like government run anything, to extremes like mixing races, homosexuality, and anything the CDC says right now.
Basically Fox news uses "Communism" as a synonym for "things I don't like"
It is different, because USA was never communist country. And those who argue by "it is like communistm" typically have only very superficial understanding of history of Comunism and of culture it had. Or none at all often.
