To understand much of our language, Gnorts would have to already be aware that our words and symbols gain meaning from how they're used, and you couldn't, for instance, determine that a swastika is offensive (in the west) by its shape alone.
In this case, the term "colored people" gained racist connotations from its history of being used for discrimination and segregation - and avoiding it for that reason is the primary principle at play. There's also the secondary/less universal principle of preferring "person-first language".
Then the dominant culture that was responsible for a lot of that injustice latched on to it and twisted its meaning, watering it down.
This is known as political recuperation - when radical ideas and terminology gets sanitized and deradicalized. It isnt some conspiracy either. It happens naturally, especially in America.
Just today I merged to the main branch instead of a master branch. This happened because Microsoft employees wanted to pressure Microsoft to prevent sales to ICE-the-concentration-camp-people and Microsoft wanted to throw them a bone by "avoiding the term master" while still making that sweet sale.
Rename that branch and everybody is happy, in theory right? Everybody except the people in those concentration camps, I guess.
The people in Silly valley with masters degrees and scrum master certificates can laugh and pat themselves on the back about all of this silliness, imagining that "wokeness" became stupid because of Marxism or something, rather than because of societal pressures (like the ever present profit motive) which they actually deeply approve of.
