People are free to dress as they please, and as said by several other members here, you can be wrongly judged by your appearance.
Yeah. And anyone who doesn't know that he/she is sized up based on appearance is an idiot. "Sized up" is different from "judged".
If someone isn't a gangbanger, but takes pains to look like one, that's his conscious choice, and it says something about him.
Too many are quick to jump on a bandwagon.
Since the old one has gotten boring, here's a new bandwagon:
If you go to a gun show, you do see a few different "classes" of people, on both sides of the table. They're remarkably easy to identify, by and large.
Like the guy with the shaved head, Doc Martens with red laces, and a big swastika tat, he's a skinhead. The dealer selling junk guns to young, uninformed buyers for twice their value, he's a scumbag. The guys with $500 shoes on, their wives think they're somewhere else, and they're looking for expensive rare collectibles. The guys in t-shirts they got free at a Microsoft dog and pony show in their late 20s and early 30s, they're single and they're looking to buy $2500 black rifles they'll never shoot. On and on it goes.
Gun shows are more interesting for people watching than buying guns. You may be right, but there are reasons why people "jump on the bandwagon" with gunshow stories. It's usually because we've been to gun shows.
