Agreed. It's much easier to state a simple yes/no proposition than a complex position.
The problem is that human motivations are rarely simple. Any attempts to understand the past accurately tend to devolve into "on the one hand, but then on the other hand" accounts, which sound like equivocation even when they aren't.
It boils down to the fact there has never been a political group, or a human for that matter, that was all bad OR all good.
Which doesn't means (here comes the "on the other hand") that the mix between good and evil isn't important.
‘’there has never never been a political group, or a human for that matter, that was all bad OR all good’’<< Does that include Adolph Hitler and the Nazi Party? Or Barack Obama and the Democrat Party?
