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".
This is only a tiny part of the reason.
The main reason is that fact-checking works so well against the right, and has almost no benefit for the right.
Why?
Because almost everything the right says is a lie of one kind or another, but almost everything the left says is either mostly or wholly grounded in fact.
So “fact checking” is an almost useless tool for the right, since it rarely ever contradicts what the left says. And yet, the right can get very severely corrected by fact-checkers with almost everything they say.
Musk and Zuckerberg are killing fact checking because they NEED misinformation to carry the day. Because if we truly understood how badly the Parasite Class were bleeding the Working Class dry just for a few extra thousandths of a percentage point of wealth accumulation, we would all rise up and bring out the guillotines to dispose of them once and for all.
Misinformation is the way they control the working class.
