I have every reason to believe that this is a clear example of Poe's Law. But that's part of the reason it cuts so close - I've had these kinds of arguments, online and in person. In each of them, you take a second, turn your head, and say "Wait...really? You...REALLY...believe that?" I've always wondered if some of the people I've had discussions with were actually trolling/Poeing...but most of them seemed sincere enough afterward.
Anyway, watch, cringe, facepalm, laugh.
