While I'm at it, what the hell:
One of the characteristics I constantly see from both ends of the spectrum is that they don't seem to put much (if any) thought into the possible downsides and consequences of their methods. So the goal may be perfectly righteous, reasonable and defensible. But if your methods in reaching your goal are counter-productive, you could make things worse.
Example? It seems to me that the Left made zero effort to examine the potential downsides to being so aggressive with Political Correctness and Identity Politics. The result? The pushback with Trump. I'm seeing the same thing here. Trump's supporters and enablers look only at the individual act, and not a larger picture, the big picture effects, or an examination of how their methods could backfire on them.
