Summary of several HN replies: “Yeah, yeah, whatever. Saying you’re sorry doesn’t cut it. You need to pay for it before we will accept your apology.” Hence, cancel culture. Edit: There’s no need to therefor assume the dude is totally changed based on one apology, but good grief people. The lesson I’m learning here is, “Never apologize. It will do no good and will simply drag the situation out longer.”
Sincere public apologies do tend to result in people going "You my bitch and whenever I'm an ass, I expect you to kiss my ass and say it's somehow your fault."
Public apologies tend to be a bad idea overall. It's a minefield of potential serious problems.
