He likely has no incentive or imperative to interrogate the narratives placed infront of him, and at surface level something like BLM might appeal to the sensibilities of some normie who came off the (gen-x)-to-modern pipeline of liberal cultural values. They think "why would you be against black lives?" or "Remember Rodney King?" - they don't wander off to the intracacies of the what or the why, what got swept under the rug in past narratives, the crime statistics, or the lies by ommission that often occur in almost every case that gets blown out of proportion, or probe the fact that BLM is an openly communist money laundering scheme. Of course any progress made in the way of opening eyes is rationalized away through advanced stage magician sophistry, casting a comforting sleepy spell that placates the discomforts of reality.

I don't think he is evil, nor is he a retard. He has simply made an investment in what he sees as socially, morally, institutionally, and financially beneficial to himself. It is almost beneficial to be delusional, because atleast you're not "lumped in with the racists" - this manifests in his head as the right thing. He's just siding with "good"™ and sticking it to those mean ole racists, afterall he like everyone else knows atleast one black with whom he is cordial. To him there is no downside to virtue signalling beyond making us groan and roll our eyes, without knowing how suicidal his altruism actually is or the wringing hands that puppeteer these movements.
