Although I believe these people can be stopped, what you are saying is actually what does help to minimize it. I can't avoid it at my current job though. I confronted them but weirdly it just does not matter whatsoever. My programming is rather complicated and undoing some of it was literally stopping myself from reacting (going into dissociated states, verbalizing in my car what I am feeling, experiencing, talking about it here and yes, walking away from those using gestures. I can't avoid it all because they don't stop. So lets say someone does not want to do it where someone can see it, they will turn around and stick there tongue out and me randomly (where I am not directly engaged with them) or start clearing their throat every five to ten seconds (that was also involved in sexual abuse programming). Some of it is wearing specific colors, grabbing at body parts or tapping body parts weirdly. Some of it is to literally direct attention. I will have cars up ahead of me who will swerve towards where I have to turn to deliver food or stop. The goal is to literally manipulate and control my behavior as well as to trigger parts in my system. I am confronting people to tell them that. The goal will be to deny the behavior (call me paranoid or I am forced out of my job.)
