He may have been, during the incident you're referring to. I'm not sure, but if he was it was impossible to tell the difference, because that's how he always behaves. I don't hate him, Jedi don't hate. That would be dangerous. And it's not even a personal dislike of him, aside from his actions. I just don't want to see him do the same thing to anyone else, especially not my family. And considering the ways this could have been handled, I think it was a good alternative.
There was little invading happening, not the way you seem to imply. A mind trick only works when it's subtle. It's just a suggestion, with just enough influence behind it so the mind accepts the suggestion that was given as it's own. It's harmless, unless the suggestion given isn't. I think 'be nice' is a pretty harmless suggestion.
You have nothing to worry about, unless you give yourself something to worry about. That isn't a threat, because I doubt most people here are going to reach a level where stepping in will be needed.
