the problem with saying that those things don't apply is that then you have this situation where 95% of people on reddit speak one way

wut. You all might use a similar writing system, but this doesnt mean redditors speak in one way. Ignoring the lack of evidence, you'd be claiming that there is a dialect group that makes up 95% of English speakers on Reddit. That's a pretty outrageous claim. Yeah, you're exaggerating obviously, but even saying "the majority" assumes a lot.

and you want us all to be accepting of the every single other dialect even though it makes up such a small percentage of the population *of reddit.

Literally every person has a dialect, including you and me. As far as a dialect being accepted, why wpuld that be by majority rule? Analogizing this to biology, is evolution not true because a very large population doesn't believe it? Bringing it back to linguistics, are the American, British, Australian, or Scottish redditors the ones that speak correct English? Why is that? Majority rule? This doesn't sound so clear thought out when you dig into it.

Finally, what aspect of a dialect or language being a minority allows it to be disparaged? Does this apply to people too?

the white part is relevant because again, statistically more black people use that dialect. the two options are that the person uses that dialect or that they're wrong and suck at english. a white person using that dialect is much less likely than anyone else on the planet just misusing a word.

This is a good example of the problems of assuming things about language when you haven't studied it. Let's take it one by one:

the two options are that the person uses that dialect (or not)

Why is it a binary? Bidialect people do exist. Dialects are just like any other language that you can learn. So this person being white doesn't mean they can't be bidialectal, unless youre claiming there is a literal connection between physiology and language.

that they're wrong and suck at english.

See, this is problematic. Why exactly is it "wrong" and they "suck at English"? Do people who grew up speaking this way suck at English and use it wrong as well?

a white person using that dialect is much less likely than anyone else on the planet just misusing a word.

Really? In what world do you live in where AAVE isn't overly represented in music and entertainment, especially hip hop and R&B. I think it's pretty off chance that someone would manage to analogise the word "woke" in the same exact fashion as AAVE and some SAE speakers without realizing it, and not ever having had heard the phrase "stay woke".

if one option is overwhelmingly more likely than any other, im going to assume its right.

The problem is your assumptions. You're not actually aware of the variation of English and language in general; not actually aware of how language works cognitively, developmentally, or socially; and not aware of linguistics in general. This all culminates in a conclusion that's built from ignorance and prejudice.

If this were physics, I genuinely believe I wouldn't get this much flak, but since everyone proclaims to be an expert on language I get a lot of really half-baked and ignorant replies.
