I also found it. It's not at all what the tweet claims, but then that doesn't make for good outrage.

I have no idea but now I know I'm not right handed, but rather my left hand is under represented in manually dexterous tasks.

I found it too. The document does say to capitalize Black but not brown or white. The style note does not have that reference, however. Either the “X” poster faked it or Delta changed it. It looks pretty legitimate based on the style note I found as in same type face, graphics etc. would be pretty easy to fake if you had the original document.

It also says why. Essentially, "Black" is a proper noun, "brown" and "white" aren't.

They don't even sell it at the big stores around where I live anymore.

Bud Light has not recovered. The stock price might have but sales are still way down. It is still mocked as the trans beer at bars. Hardly anyone orders it anymore. Walk down Broadway street in Nashville. You won’t see anyone drinking it.

Didn't you know? If you drink Bud Light, you become trans. Scary times

I don’t have a problem with capitalizing or not capitalizing but I don’t see in the document a reference to it being a proper noun but rather a formal ethnicity and thus the capitalization.

Man, I really grew up listening to you guys tell me not to believe everything you see in the Internet and....well...here we are

What made me laugh is that they do serve it at Kid Rock's Big Ass Honky Tonk and Steakhouse and never stopped, along with Bud Light Lime. https://www.kidrockshonkytonkandsteakhouse.com/menu
