"Preference cascade". Ding ding ding!!! I could hear the alarm bells in my head as soon as I read it.
Liberalism shows all the signs of being a spectacular cultural bubble. It's a fiction, it's hyperbolic, and it's getting harder and harder to convince yourself that there is any merit in it whatsoever, let alone be able to convince others. "Black Lies Matter" the SJW movement and Feminism are in the same spot that the Bear Stearns Mortgage Desk was in January 2007. They run around singing everything is awesome, but in reality the ground is evaporating under their feet.
This election could very well be the moment when the cultural bubble bursts.
