I get that you can't fathom it. But so what? Nobody put you in charge of deciding when people should feel unsafe. Or whether I should have sympathy for those who do. Or whether we, as a community, are willing to let a lot of otherwise useful contributors walk away because they don't feel safe.
I don't want to be a hero. Heroes need villains. I want a good conference, where everybody feels safe and welcome and we can all focus on learning. And this seems like a step in the right direction.
Hey! Just because I don't care doesn't mean I don't understand.
It's telling that Homer's redemptive characteristics are that he's capable of loving his wife and his children, and through his love, he's willing to realize that his opinions on things, his actions, are not perfect just because they're his. He can admit to being wrong; he can start caring; he can grow, ever-so-slowly, as a man.
The point I'm making in quoting him is that caring and understanding are distinct axes. You can care/understand, not care/not understand, not care/understand (Homer), and care/not understand. Each of these ways of being tends to bring different results.
