It wasn't intended to be snarky, nor unsubstantive, though I suppose that without the necessary context or self-awareness it could come off as either. I'll admit that I may be in my emotions somewhat.

The culture I would like you to try for is one in which people don't feel comfortable questioning (or, rather, vociferously protesting through abuse of the flag feature) the validity of posts celebrating the lives of black luminaries. In general, the level of soft racism on HN is disheartening and certainly warps how I tend to respond. I join you in wishing that I didn't feel the need to mirror a lack of extended dignity with indignation.
I do think it's hilarious that the one time Google doesn't drop a relevant search term in the middle of a query is for something like "black haired man." The way it treats terms, you might expect it to drop the "haired" and return pictures of black men, but no, it's almost exclusively white dudes with black hair (never mind that black and brown people also have black hair).
