Marcel, firstly, I want to thank you and the other mods (particularly @DerAdlerIstGelandet) for your patience with us on this challenging thread. You do an amazing job managing a thread that clearly sets emotions running.
I also think you do yourself a disservice. I can't recall a single post of yours that has been deliberately offensive or factually incorrect. You've always posted content that has sought to inform and enlighten rather than tear down.
I have no problems debating with people who think America should pull out of Europe, stop getting involved in international affairs, spend more money CONUS etc etc. I get frustrated when folk won't engage reasonably to discuss those topics, even when couched in historical precedents (e.g. appeasement, isolationism etc.).
The nub of the problem is that we're in an era of (to quote Rudy Giuliani) "alternative facts" and there's no willingness, in certain quarters, to even debate whether information is accurate or not. In this case, there was an article posted that was full of inaccuracies and misrepresentations. Efforts were made to point out the fallacies but instead of engaging in the discussion, Bill just turned and ran. We could have done a better job articulating our concerns with the content but, equally, there has to be a willingness by the other party to listen...and, frankly, they aren't.
My biggest fear for civilized society is that we seem increasingly incapable of discussing facts, let alone striving to find common ground. The internet has become a megaphone for people to scream their preconceived perceptions at ever greater volumes and, unfortunately, the sheeple are following blindly.
