A 1000 times yes. But, with one proviso: It is ethical, right, and good to cut off all ties with people who actually do violate social rules and hurt others.

A 1000 times yes. But, with one proviso: It is ethical, right, and good to cut off all ties with people who actually do violate social rules and hurt others. It's better for everyone, including the person who did the deed, because they will learn fast that it is unacceptable. There should, as the original post says, be no exceptions for skill or usefulness. In my time, I've entirely cut off people who I've learned have hit or abused others in any way. I don't care if it's a man sticking his hand in a woman's pants or a guy hitting his boyfriend or a woman verbally abusing her man, or any parent mistreating their child. (All humans, of every gender, age and background, do evil and hurt each other equally.) I've taken a lot of heat for this, and lost opportunities for money & fame, but you know what? I can sleep easy. I'm not losing my own sense of what's right by drips and drabs of attrition. That said, you can't make it top-down. It'll never work. There's no way to dictate that others do this, no community "rules" that will work, unless people are willing to look hard at themselves and ask, "Is this the kind of behavior I want to condone? Do I want to even be in the same room with a person who'd act like that?"
