The worst place I've seen racism is the YouTube comment section of police bodycam videos. I swear the >50% of the videos will be of white people but whenever it isn't the comments are filled with racist stuff.
Infact I went to a bodycam YouTube channel and clicked on the first one from an African American male and picked out some comments sorting by newest. Here are some examples:
"always the same breed" (11hr ago)
"Pew Pew. just saying."(13hr ago)
"Bet they got an OR bond cause of "racism" "(51 minutes ago)

This video is 2 months old.

And this comedy:
"Your Sargent don't want you arresting [censored n-word]

Because the crime stats shows how they ruin and destroy your country USA [fist emoji] [American flag emoji]

Government don't want Americans to realise how immigrants come to America [American flag emoji] to commit crime"

which... isn't even true, Immigrants have been about equal or even lower with the White US-Born population

Anyways, what I find the most disturbing about the YouTube comments is that it's so surface level compared to something like 4chan or other obscure forums. they're shouting their racism to everyone who will listen

4chan is a flaming trash heap
