In regard to the censorship of politicians and people in general, that is really a consequence of the pressure put on society to be politically correct from those radicalized by the aforementioned harmful idealogy. I won't list any particular schools of thought, political parties, or people as the ones responsible for the radicalization.

Though that does conveniently play into their hand by setting the tone in society for everyone else to follow and weaponizing the press to put pressure on the civil servants that may not subscribe to their idealogy. It's like a feedback loop that allows those benefiting from it to manufacture the circumstances necessary to push their policies.

Though a lot of that is just conjecture on my part based on what I've observed so far.
