It’s your opinion that he was right, but others don’t share that and let’s not go through the whole thing again please? I mean you can if you want obviously but it’s not going to make everyone agree. Not trying to be unpleasant to you, i just don’t see the benefit in having the debate again when the person who brought it up has already apologised
As for people behaving unpleasantly, generally nobody thinks that they are the one behaving unpleasantly in any situation so if anyone was out of line maybe that’s better handled directly in a pm
