Sadly, some people only seem to know how to intimidate, invalidate, shame and manipulate others. Anyone can probably do that under enough stress, too. I think it happens a lot more than we like to think. We can be a vicious species sometimes - perhaps out of vulnerability, ignorance or desperation as much as malignant intent? I'm not a psychoanalyst, just curious (and partly out of self-preservation, tbh!)

This can do a lot of damage. I am reminded of concepts in Schema Therapy known as Subjugation, Defectiveness, Ostracism, and Incompetency schemas. I suspect any of these could have their origins in being psychologically "overpowered" or manipulated in the past, and variants of such experiences.
