Penguin, do you see anywhere in my post where I make reference to their looks? Did it occur that leathery and weatherbeaten, not to mention pretentious, undesirable, or "tethered" has much more to do with behavior than looks? You're very young. I will offer you this: learn to set standards for acceptable conduct in those with whom you associate 1. not too high, or they will be impossible to attain and you'll find yourself alone, 2. not too low or you will become a human garbage dump, willing to accept anything.
I recognize that there is a school of thought that thinks all behaviors are equally acceptable. I didn't go to that school.
I googled their definitions and they were all visual adjectives. You are either using them as slang (which is wrong to assume that everyone knows) or just do not understand their definitions.
I very well know what pretentious means, and if you stop enabling the behavior, they will stop acting that way. There are many pretentious people out there with very good reasons to be so, but even more of them don't have any.
Tethered? Do you mean emotionally dependent? I've met those people, they're quite frightening, but I've learned to see past it and be nice to them anyway.
You seem to have taken my notions too far. I did not mean that I will always tolerate any kind of behavior. I meant that I will never condemn any person as 'undesirable', but focus on what they've actually done. My reason for this is that judging an entire person by their actions is inductive reasoning, which is unsound. Take the black swan paradox as an example.
Behavior that I will not tolerate include: bullying, crime, violence, and acting upon extremist notions (this includes anything listed under Rule #14). However, I'm cool with anything else. There's a way to deal with any behavior or condition, one only needs to manage the negative aspects and enjoy the positive ones. For instance, I was always mean to the kids with mental conditions; after telling a joke about them to one of my friends, he went on a rant about how cruel it was. I then realized my mistake, and found ways to not be such a d-bag to them.
