That sentence also jumped out at me.
In expounding on this point, I would say that the left is all consumed with emotions. They base all their policy positions on emotions. All policy positions are either “nice” or “mean” - they make me “feel good” or “feel bad”.
Ascribing emotion to the opposition’s genuine “difference of opinion” is simple projection on the part of the left.
When two sets of folks have a major disconnect between them, each side will tend to perceive the other that way.
