How is it racist to make fun of this criminal when he legitimately looks like a Neanderthal?

"Legitimately"? The messy unkempt hair and poor excuse for a beard are the closest he's got to a neanderthal. His lack of pronounced eyebrow ridges, cheek bones, regular sized forehead and regular sized nose that protrudes past his mouth/jaw entirely differentiate him from that species.

I never said it was racist to make fun of the criminal. I just think it's laughable because neanderthals never lived in Africa so I've never understood the obsession some of the people here have with calling black people neanderthals. Just like how I don't think it's racist when someone calls an asian person "chinese" even if they're clearly from Korea, Japan, or Vietnam. It's more like "oh, you just can't tell" making it obvious they've never left their white picket fenced in yard in their small home town.

Also, if you're uninterested in being overly sensitive when making fun of a violent criminal, you should probably revisit your assumptions about the other commenter's mixed race kids. They may be adults who may also be violent criminals who've been in and out of jail, and if that were the case, would you care what adverb someone used to describe their skin?

Exactly which, and exactly how many offences does a child have to commit for you to transition from defending them from a Racist to making fun of their mugshot?

Do mixed race people typically look like Neanderthals?

No present day humans look like neanderthals at all.
