There's a difference between noticing and "noticing". By now, claims of "noticing oppression" are well past the point where they should be uniformly regarded as crude dog-whistling.
This is funny to me. "You saying that I enslaved you, barred you from education, and divided and slaughtered your family is actually a subtle dog whistle against white people"
Yes, indeed. What you just quoted is in fact the language of crude conspiracy theory, not even of the most cursory thinking about real-world systems and structures of oppression.
