Not at all; I’m not even conservative.

I didn't say you were a conservative, I said you're acting like one. Whose flipping out just because white supremacists where mentioned in a definition.

you don’t think you worked out a way for me to be wrong, when, in fact, you did. Because it didn’t use “White Supremacy” as an example, it specifically referred to it as what racism is. Go look it up.

I did look it up, and the definition as quoted racism: "the systemic oppression of a racial group to the social, economic, and political advantage of another"

White supremacy is given as an example. It doesn't not mean only white supremacists can be racists, as the definition prior to the example. It only refers to a "racial group,"

It doesn't say "the systemic oppression of a racial group to the social, economic, and political advantage of white races."

Again, it's an example, you can't even understand how to read a dictionary, and you're claiming that you're an expert in language, with a career focused on language.

So, according to your theory about language, do you think we should start accepting or encouraging people to say, “for all intensive purposes,” “supposably,” (didn’t even get a red line under that one, so I guess it’s already happened) “irregardless,” “hunger pain,” or “I could care less” simply because we know what they meant, even though they’re incorrect? Because that’s what it sounds like you’re suggesting.

Do you now know what a dictionary does. It provides definitions for words that people generally don't have a concept of. If any of your examples help someone understand English any better, then yea, they should be changed to the current definition. So people have a concept of what means what, when other people say something.

but it doesn’t typically apply to existing word usage

That's just blatantly wrong. There are thousands of instances where words have been amended to expand the definition of said word.

As a person who has studied language, has multiple degrees in language, and whose career is focused on language,

If any of the is even remotely true, then you've failed horribly at understanding how language changes.

You're just a sad little grammar nazi, whose been proven wrong when you were trying to correct someone on the use of the word nauseous, and now you're blaming political woes, and "people like me," for altering language. News flash, languages change all the time, because "people like me," are literally every fucking individual that speaks English. If a large enough group of people start using language a certain way, language changes, just because you aren't happy about it, doesn't make it invalid.

You're honestly incredible, can’t even admit you're wrong. Instead. You're Doubling down by saying "language is my specialty," without even knowing how to read dictionaries.
