I actually don't even know what that is.

All stereotypes are bad, but as a mixed black person, I'm frankly more worried about the "black people are violent" stereotype.

Which one? There are various different stereotypes, and many have roots in some rather shameful aspects of History (e.g.: treatment of slaves). I understand the down votes on this question, however I do suggest people research various stereotypes revolving around 'black' men and women. I personally found it rather shocking to discover how many terms, which are used for a general prejudice of all people, originated through harsh exercise of bigotry.

I don't.

It's been on my mind lately because of some Trumper relatives who are currently screaming about how "Kamala Harris is a slut."

She dated Willie Brown for a year, just before he was mayor of San Francisco in 1994. He had been separated from his wife for twelve years at that point, and she was also single when they met and started dating. Even so, the Fox News crowd is enjoying the refrain "She stole a black woman's husband!!" (predatory promiscuity)

They also parrot the phrase "She slept her way to the top." She was already an assistant district attorney when they met. He was the speaker of the California State Assembly and was known for handing out high paying state appointments to his friends. He appointed her to two boards- the Unemployment Insurance Appeals Board and the California Medical Assistance Commission, consecutively. Both paid well and gave her experience and connections in politics/public service, which may have helped her when she ran for and won the elected position of District Attorney fifteen years later, but certainly did not guarantee her the job.

But any excuse to be publicly racists and diminish the accomplishments of a Black woman while sexually shaming her get pounced on with enthusiasm.
