Hey, @focus.folks.
re: black and white
Can't really disagree, though in my own experience, there are some decisions or some concepts that are more black and white, more this way or that, than not. Just as we can ignore the fact that 'our guy' is doing the same thing the 'other guy' would, we can also complicate or overthink situations, creating nuances that really aren't there.
re: Them or Us
Someone benefits from an adversarial mentality, but it's usually not the actual combatants themselves. Thankfully, in many cases, someone in the Us category will overplay their hand because its part of their nature. And at that moment, more people recognize that both sides have their human beings, if not some merit.
