Statists, notably in this case those of the left variety, have raised tolerance to level of political dogma, but embedded in that tolerance is an unwillingness to call out their own side for intolerance. As explained in this very well-written article from a leftist point of view,
...imagine some liberal US Muslim leader, when he goes on the O’Reilly Show, and O’Reilly ambushes him and demands to know why he and other American Muslims haven’t condemned beheadings by ISIS more, demands that he criticize them right there on live TV. And you can see the wheels in the Muslim leader’s head turning, thinking something like “Okay, obviously beheadings are terrible and I hate them as much as anyone. But you don’t care even the slightest bit about the victims of beheadings. You’re just looking for a way to score points against me so you can embarass all Muslims. And I would rather personally behead every single person in the world than give a smug bigot like you a single microgram more stupid self-satisfaction than you’ve already got.”
This unwillingness on the left (and statist right/neocon/#NeverTrump lot) to call out their own is due in part to the embracing of politics as a religion. As noted in this awesome article:
Liberals...have made politics their religion...What they really want is liberal Sharia law, a secular theocracy.(emphasis added)
The minimum wage, gender equality, nationalized health care, and global warming—whatever their practical virtues—are not just expedient policy prescriptions. They are essential aspects of the liberal fatwa...the left is having a nervous breakdown in the wake of Trump's election..because, for them, politics is the means to secular salvation...political failure is not just a setback on the road to a more stable society—it is a blow to their very worldview. Opposition to their program is not just wrong-headed, but evil...Question them and you are not just wrong—you are a heretic.
I believe you are on target, that credibility and hypocrisy is taking its toll on the haters of America. My guess is the #WalkAway movement and other similar efforts are a result of people getting totally fed up with this "good for me, not for thee" attitude, so wonderfully on display at the NY Times.
Very good article in that link.
