In the mind's eye, an image forms. An alternate version of that segment from The Boondocks TV show.
A man pulls off his belt and raises it, standing over a small child. The child cowers. The man screams, 'I am about to ruin your ability to trust anyone or love yourself, ever again!' But then he stops, looks down at himself, and says 'Oh, wait. That's right. I'm straight. Come on, kid. Let's go get ice cream.'
They are nested concepts. Manipulation is a method of convincing. It is just convincing using surreptitious/covert means.
