Editing someones reply even off topic is something i have never seen especially as such talks are common (too common you're right) but as i say why not start with people who do it alot! I gave you info on an editor that does that and you say a make a personal attack? Lots of people have told him about it and its the nature of the content thats the problem. Rants and Conspiracy theories, do something about it or don't, don't matter to me. And in the part of the world i'm from the phrasing "If you cannot act civil, YOU will be dealt with accordingly, like it or not" indicates a threat, because of good faith i don't take it that way.
