Sorry, this is textbook bigotry to me, and I am dismayed by the fact that this way of thinking infested the American academia and half of its political system.
As a young guy in the 1990s, I knew a few old bigoted Polish Catholics who disliked the Jews because they "killed Christ". Being naive, I was thinking back then that this kind of heritable guilt was on its way out. Nope, I was wrong. The ideology that you describe is arguably even more nonsensical, classifying totally unrelated ethnic groups as "white-adjacent" and assigning them the same or even greater level of malus points.
The most absurd thing about your argument is that OPs ancestors probably lived under British colonial rule more recently than American blacks under their masters, and approximately at the same time when Jim Crow was rampant. And in 2022, white liberals treat them as undesirables once again, and once again for racist reasons; only the details have changed, but not the principle: Sorry, there is too much of your people on the campus already. Begone.
