pwBPD expects undying loyalty and praise, whilst treating everyone terribly

A pattern I've noticed, this person expects to be worshipped and praised by everyone. Be it her parents, her siblings, me, or a random person, this person never wants to hear any "bad" things. She reserves the right to treat people like absolute crap, but expects to be praised and heralded as the best thing since sliced bread. I tried explaining a basic issue to her, and she blew up on me, and claimed that me even hinting at her not being perfect is akin to hate speech.
