You probably do have friends and family that are capable of it; they're just good people and choose not to use the tactic. It's a dirty trick and emotionally abusive if you also target other emotional vulnerabilities.

I see it the same way as arguing or interacting with someone who is weaker or smaller than you. Just because you can toss someone around like a rag doll, doesn't mean you're going to or that it would even occur to you.
