The KKK are too old lazy to be a threat

I understand if they wanted to make a movie like this just for hell of it but when you bring in "based on real life events" you gotta have some fact(yes violence in the 60's i know but this a modern movie).All the kkk do nowadays are stupid marches, call it a day and go back to their trailers. They aren't even the violent ones anymore, most normally get beaten up or stabbed by the far left. Felt funny about this from the moment they mentioned "far right terrorists". I don't mind a movie that brings up something nonrelevent and gives it a good spin but this feels more like lowkey political manipulation than anything.
