Also you’re ignoring that he’s taking a class about getting to carry concealed weapons. He’s not just dressing like this to do his errands. They’re not judging him based on looks alone. They’re judging him based on looks, actions, and a comment he made that he expects things could dissolve into a dangerous situation at a class. A mentally healthy person doesn’t expect things to pop off at a safety class. If he thinks it’s likely at a safety class, he definitely thinks things might pop off at a movie theater, a festival, a mall, a doctor’s office. I don’t want this nut showing up to any of these places with a gun, I don’t care how he’s dressed.
