Why is BPD so stigmatized?

If BPD is mostly caused by childhood trauma and abuse, why is BPD inherently seen as 'evil' by neurotypicals? It's not like anyone chooses to have it.

Personality disorders in general seem to be way less acceptable than even something like depression, or autism.

I just can't fathom thinking a person is evil even knowing that they are suffering from a severe mental health condition.

The whole stigma behind it feels forced to me. People hate you for having too many emotions? For experiencing trauma?

It feels like you're being punished for simply existing. You can imagine how exhausting that is for people with BPD.
