Then there is WHATABOUTISM: "a variant of the tu quoque logical fallacy that attempts to discredit an opponent's position by charging hypocrisy without directly refuting or disproving the argument."
We Tricky Monkeys love to play the "what about game;" it is a scourge, it is maddening, it makes hash of sensible arguments. It is employed across the globe. Sometimes you just can't get past it. It's a deal-killer, brain-numbing, a great tool in the fabulous disinformation dystopia.
Sometimes the only thing to do is walk away. WHATABOUTISM is a dead, black hole for any kind of sensible discussion. Cooler heads must refuse to play.
