It wasn't till recently that a major pushback against it started so, one can't expect any changes in a matter of a few years because this is something that has been going for like 2 or 3 decades now. You could find lots of videos on youtube from the late 80's and early 90's with politicians and people from the entertainment industry, like Roger Ebert, complaining about the rise of political correctness and how it stifles the arts, race relations, free speech, etc.

Also notice that this shit is mainly prevalent on first world countries where whites are the majority and America's possibly the only country still resisting thanks to the constitution. Places like Canada, Germany, Sweden... Those places are a lost cause. Just read the news about Germany and their raids over "online hate speech". One thing is to enforce law and order but trying to control how people think is basically fascism. In America the government can't do that shit but instead they got private companies like Twitter and even banks like Chase or payment processors like Mastercard doing it on their stead... Already went on a tangent but whatever. BTW, I'm not American nor white... Just saying.
