It's a very typical kind of piece that starts with a self-evident, humble truism, i.e. "If you don't have anything to apologize for don't, if you do, apologize", and a Hamilton example to kind of obfuscate the tone and then the actual message comes when you bring in Andy Ngo and the 'far-left'.
Even the beginning is silly. Bringing up the cultural revolution followed by "obviously I don't intend to compare anything to the cultural revolution". Okay, then what's the point? It's how all of these articles work.
