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".
Presumably you liked the fact checkers before because they were of the same political persuasion as you. Now that Trump is in power would you prefer if Musk/Zuckerberg placed right wing fact checkers in place and punished any opinion which is outside of the platform's Overton window?
Musk removed picking fact checkers and replaced them with community notes. Zuckerberg says he'll do the same. Isn't that the societal accountability that you want?
Or perhaps the GP liked the fact checkers because they were on the whole doing a good job of actually checking facts.
I don't know if that's true or not; I haven't been on social media in years. But it's an incredibly weak argument to assume that someone only likes something because it aligns with their politics.
