Judgments are made all the time based on how people present, sometimes things within their control & sometimes not. That doesn't make judging people based solely on appearance a smart or desirable thing to do, and I personally would argue it can actually be dangerous, as things you see as positive (blank skin & whole jeans, presumably) can lead you astray if you're trying to suss a person out.

For instance, your supposition that someone with say, a full sleeve & a platinum Mohawk couldn't be an accountant. I (with the sleeve & the mohawk) actually do happen to work as an accountant for a large, old & very high end jewelry store. I make excellent money & have excellent benefits. Before a serious illness forced me into civvies, I was a fire service medic. If you'd be so completely wrong about me if you saw me on the street, don't you wonder what else you may be wrong about when judging people solely on the way they look?

Look, you're well within your rights to not care for tattoos, or "ripped jeans,", but you are absolutely judging people. You live your life the way you see fit, but you may be missing out on all sorts of people & experiences!
