I'm glad you haven't had any interaction with these kind of people, at least not outwardly. I think it's important to think about someone who has struggled with abuse or is currently a victim of it. It clouds your thinking and judgement, it feels normal and familiar. I believe there are too many people in this world that could benefit from such information.
You're right about nuance. Everyone displays some of these traits some of the time, but when talking about abusers who weaponize these traits to take advantage of vulnerable people it's a very real problem.
Yes, please!
