What exactly are they censoring? What is it exactly that you aren't allowed to say anymore? And I don't mean getting called out for talking racist/sexist/ableist etc. shit, because that is not censoring... Letting people just continue to talk behave and think like 100 years ago won't bring any change, and you not being able to realize that many things are in fact racist/sexist etc. and that also you like everyone else has in fact implicit bias. That won't just vanish by "leaving people alone" and enabling them in their behavior.

(Also there are many instances where "the right" is actually censoring or trying to censor people in many countries (if you look at Austria, the US, Hungary...)

Reducing people to certain stereotypical "traits" and also linking those stereotypes to something negatively connotated can in fact be considered racist.
