But trying to figure it out, what was her issue?
No doubt a number of factors.
But, and I know this won't be a popular opinion here in the liberal land of Slashdot, but I think a liberal (in the new sense of the word) education played a big part. She used the ultra-left's language ("that's my privilege"). I'm sure that included plenty of material about how cops are evil and bad and whatever else, and she treated them accordingly. And of course, her complete entitlement mentality, the foundation of leftist politics.
Beyond that, probably parents that didn't beat her ass and/or tell her no enough, if at all.
Nobody calling her out on her bullshit, as and before it escalated.
And let's not forget, like most women, just won't fucking listen. And I'm no incel. My wife has the same fucking problem. Doesn't understand why I get upset when tell her I want Klondike ice cream sandwiches and she brings home Klondike ice cream bars. No sweetie, they're not the same fucking thing!
