In our current example, no nuance is allowed when it comes to the evil commies. Looking at the situation through Putin's eyes means you're defending him, and of course that's just because you hate America, thus because you obviously hate America, then you must hate me too.
Your exchange with Vangelo is a bit different, but right along the same lines. Lots of "if/then - either/or".
I remember an early on exchange with a Q follower over yonder next door. I was suggesting that amidst all the rah rah flag waving, it might be a good idea to consider the harm much of U.S. foreign policy inflicts on others around the world. Response? "Why do you hate your country so much?"
Or on the Trump thing. Didn't matter how often I expressed how little I care for Joe Biden either, because questioning or criticizing Trump automatically meant that I'm a far Left commie radical. End of story.
So this is the binary way of seeing our world that's getting on my nerves these days. Bringing us back to topic, IMO the greatest threat for a major conflict is this type of thinking. Basically "if you're not with me, then you're against me". Or "either you're with us, or you're with them".
