If they want to cut down on confusion it should be DOAS. Anyone is American if they are born here, even if their ancestors were enslaved somewhere else. I agree with Wendell and the other posters tho, it is divisive.
If someone who is ados says something negative about other black peoples, it is not representative of all of us. If one of them says something about us, it's proof they all hate us and want us to fail. If one of them says something supportive of ados, they amplify it and and say they don't hate other black peoples because if they did, this one immigrant who gets it wouldn't be on our side. It's just like white folks and their one token they use to say they can't be racist because this one black person says it too.
In the end, attitudes we have toward one another were all formed in part by WS which did not want to see a united black coalition across peoples. Ados can present their agenda in a way that doesn't shit on other black folks, if they wanted to. Who gets paid shouldn't even be an issue until something gets agreed to. It's only common sense it should be people whose descendants were American slaves.
They are just giving disaffected folks an easier target to go up against. Targeting other black folk or immigrants who socially are at the bottom rung like the rest of us, but within in striking distance for an easy win, is a lot easier than targeting WS.
