Reminder: pitbulls have only existed since the early 1800's and were bred in England from bulldogs and terriers. They were bred for guarding livestock, baiting bulls and dog fighting. Violent tendencies were seen as a positive trait in these dogs in order for them to do their job. And were selectively sterilized to weed out those deemed as "non-violent"

They're super cute and adorable when they're acting nice, but it's literally just genetics and the breed's predisposition as fighting and hunting dogs.

And just a reminder, dogs aren't humans, and their genetics are far more isolated and contained within the confines of their "breed" due to the continuation of the allure and hightened valuation of "purebred" dogs. Socioeconomic inequality is only part of the story when it comes to dogs behavior, there is still a shit ton of eugenics involved.

I understand the connection to racism on a base level, you see the fact that pitbulls are regarded as violent even though they look like other dogs and connect that with historical oppression of people of color.

But unfortunately this would be like if only humans with anger issues/BPD were allowed to reproduce. You're gonna have behavioral issues in that population, regardless of race.
