ADOS did NOT just come out of nowhere, there are a multitude of factors that caused its rise, such as discontent with the Democrats, the need for a Black American-specific agenda, and how immigration harms Black communities and yes, once the issue of immigration started, many people began recalling instances of bad expiriences with immigrants, both Black and latino and this ranged from low wage workers to highly paid people.
When it comes to the push for reparations, while immigrants certainly do not have power in that arena, to act like the children of immigrants or naturalized immigrants haven't voiced their opposition to reparations, citing their own personal successes as reasons why we shouldn't get it.
You can't pull any instance of me on BGOL shitting on Democrats, I'm a lifelong Democrat, never voted for a Republican in my life, Blue Dog Democrat John Bel Edwards is probably the most conservative person I've ever voted for. You also can't pull any instances of me shitting on immigrants.
The point is this
ADOS, no matter how flawed, messy and useless it has become, did not just start because people woke on a cloudy Sunday morning and said "Fuck the immigrants"
