Or are they subject to changes based upon the opinions of the loudest voices?
For example..... in the 60s it was acceptable for black people to be called "negro" or "colored"... even by black folks. Then it was changed to "black".... and within the past decade or so, you are wrong if you don't say, "African American".
And then... the new rules coming out with "code words" for racism.... for example, there is apparently a movement to turn the word "thug", which has been used for centuries into a strictly racists (against blacks) "code word" for "Nigger".
I mean, honestly, who can keep up with all this bull****???
She didn't get it.....
That is exactly what the PC world wants us to do. Be forced to use whatever terminology they come up with this week that is "acceptable" to call someone. Thus creating evil hateful racists out of people who were adults in the 1970s when it was the "acceptable term" to use word X... and who didn't have the time or care to keep up with the fact that within 30 years the "acceptable" term changed 4 ****ing times since then.
Its the easiest way to discard any opinion or shut down any disagreement with the political "fad" of the time.
For example... as a result of all the idiotic looting and burning in the name of "BlackLivesMatter" people are trying to get the word "thug" turned into the new "Nigger" so anyone who ... rightfully calls a looter a "thug" is being racist.....and therefore, we don't want to listen to what you have to say about these criminal acts because you are just an evil evil racist!
In short.......Its how they reach this....
I also don't think that there's much basis for saying that manners are changed based upon the "loudest voices". It seems to me that those who oppose so-called political correctness are just as loud as those who endorse it. Most manners that are referred to as "political correctness" just come down to respecting how people identify and respecting their boundaries.

It's a good thing being polite, but PC is being afraid of speaking the truth.
