I've never gotten violent. I'm a passive person and believe in passive resolution. But my voice gets loud and commanding and I've been mistreated by a guard who mistook it for agression. I'm sorry you go through that too. It always morphs into something slightly different and all the signs tell me it's true this time. Everyone's facial expressions, tone, body language becomes hostile and evil sounding. Very sinister. It's very scary but I go someplace alone and don't talk unless I have to. It helps. I just get stuck in my head and time passes.
