Political correctness is partly based around that, people pay lip service to it to reap the benefits from being seen as virtuous without having to do any good deeds or even believing it.
This is IMO the true danger of PC. Anyone with half a brain can avoid a list of 10 slurs and be as bigoted as they want because society is hyperfocused on language policing.
the PC subplot of recent South Park season was really great. all the PC bros were just virtue signaling. that & PC language is an excuse to jump down the throats of people who badspeak
It is possible to say all sorts of wacky stuff with the correct PC words and not possible to make any constructive criticism or argument without it, not good for anyone.
If we paid attention to what people were saying rather than how they said it (i.e. we stopped caring if they use "bad words" and just listened), we would catch more bigotry, not less.
PC also makes people hypersensitive to imagined sleights and hidden messages, it makes it possible as you say for real bigotry be communicated through a culture of code and conduct.
That is true. PC also go beyond the word choice and into the realm of acceptable opinions and arguments, the highest value is no longer to defend others right to speak when disagreeing
