I was sympathetic to this line of reasoning but I feel it's repeatedly shown to be self-defeating. What chance have the proverbial good-guys got if, even after _proving_ some modicum of good will, people will nonetheless condescend any attempt to influence bad/wildcard actors? It feels great to tell someone they 'should've known better' but I'm convinced that that's basically void of cautionary utility.
