The poster has made a good point.
Possibly, though not necessarily the one he intended.
1. On the Internet, "certain" websites have been removed because they carry politically incorrect comments.
That needs clarification. Some websites (or more accurately, domains) are taken down by national authorities for hosting
illegal material but not for just anything “politically incorrect”. People running individual websites can and do remove or refuse to include material they don’t want to for all sorts of different reasons, good, bad and indifferent. The owners of that material will retain the right to try to put it on another website or to host the material themselves.
2. There are some TV shows from the past that can no longer be aired.
Again, I’m not aware of any TV show that
can’t be broadcast just because of “political incorrectness”. There will be plenty of TV shows no broadcaster
chooses to show due to either their opinions or their perceptions of viewer opinion. They’ll ultimately show whatever will make them the most money and not show anything that puts their income at risk.
3. There is an infamous silent film that cannot be shown except to university students who are studying the history of film.
I’ve no idea which film you’re talking about. I wouldn’t be surprised to find out it’s either another case of people just
choosing not to show it or an specific legal issue rather than just opinion based “political incorrectness”.
When the Democrats regain the White House in 2020 (and they will, one way or another), we will see censorship the likes of which even the most pessimistic person could never have dreamed of.
The two major parties in the US are, at their core, very similar which is why general policies like this rarely shift very far even when you get a shift in power in government. When purported key issues for each party, like government spending, gun control, the drug war, immigration and the like never see real fundamental change in policy between governments, I don’t see why a less mainstream issue like censorship would change much either.
