If liberals hate something, the argument goes, then it must be wonderful and worthy of aggressive defense. Each controversy reinforces the divisions and the distrust, and Mr. Trump counts on that.
What may have begun as a policy or a tactic in opposition has long since become a reflex. But there is an obvious price to be paid for essentially becoming a party devoted to trolling.

It stopped being a movement based on ideas or centered on principles a long time of course, but calling conservatism an irrational anti-liberal reflex is good description.
