I hate it when people say "They look exacty like I'd expect them to look like" after someome does something bad

[ALT text: youtube commenter gabbyramirez1670: “This guy looks exactky like you woukd expect him to look like lmfao"] and context video (boring warning - simply shows a man crash into girl’s kart after being annoyed that her and the people ahead of her keep on stopping on a toboggan)

Bad people come im all spots and stripes. I think that’s all i need to say. It’s dangerous to ever assume that people who outwardly look similar will have the same behaviour patterns.

I’ve just been seeing so much of this online. It’s rarely racism or similar but… what’s the benefit of making this comment? “Ah, funny, i’ve had bad experiences in my past with someone who looked similar to this!” It doesn’t make sense to say such things to the ether, to an audience of 7.5 billion humans.
