I’m not demanding anything, I’m countering your point that silent disapproval means that it’s shunned upon. It’s not. I’m not blaming anyone for not stepping in, I’ve also not stepped in several times, but be aware that that’s enabling.

“Society is against this kind of behaviour” no it isn’t, it fucking isn’t. Sometimes individuals have good reasons, whatever, but the conclusion is that abusers feel enabled. And I’m not even touching the disparity between genders in these situations.
