There was a weird incident in class where a good amount of my classmates, including some who were POC, believed that black people were biologically more aggressive based on anecdotal experience.
I'm white but I was arguing against this because it made no sense. As a possible explanation I argued that black communities are typically poorer because of history (slavery, segregation, ect) and that poor and desperate communities are whats more likely to be violent.
It seemed to get them to pause for a moment. I'm sure I wasn't as nuanced as I'd be now but I was a dumb reactionary teenager talking to dumb reactionary teenagers.
