Again, you notice the argument gets diverted via strawman into something else entirely. When the data doesn't exist to support the argument there ideological promoting his hoping to accomplish, they just transition into a new argument to divert from the initial one.
You would think someone who had convinced themselves so deeply that systemic or institutionalized racism didn't exist would easily be able to provide the supporting data to prove why it does not exist in financial institutions, housing, education, healthcare, pay, employment, advancement opportunities, positions of leadership and so on. Obviously they should have the access to that if they have formed these beliefs based on it. Instead, you eventually get the claim that it's simply not worth posting because it would not be understood. Surely, even if you truly believed that, you wouldn't just assume that everyone else here wasn't capable of interpreting it. It appears the bigger reason is that it simply does not exist, and this is all a tactic to deflect from that.
