The only reason why men think all BPD women are hot is because they only tolerate evil behavior from hot women
Most men with self-esteem and options won’t tolerate the emotional instability and turbulence of BPD if the woman isn’t attractive, so only the attractive ones have access to non-loser men to inflict harm on.
A lot of people who work in psych say that most BPDs look average or below if anything. But the top 1% hottest BPDs rise fast socially and do terrible things to many otherwise socially integrated people, while the average BPD woman is overweight with 3 baby daddies and on-and-off dating a guy with DV allegations.
It’s the same thing as with psychopaths, people think they’re smart, but most of them are actually slightly dumber than average, it’s just that the top 1% smartest ones get away with it, get successful and do lots of damage, while the rest just ends up in prison for short-sighted crimes.
Another thing is that men like to call any toxic ex with Cluster-B traits BPD since it gives them higher social credit than if they said that she was NPD, which is seen more clinically and negatively. Most of the time they’re talking about smug upper middle class art hoes, the Phoebe Bridgers types, and in those cases, their behavior is more often driven by standard narcissistic entitlement.
