I think the reasons there seems to be more of this kind of thing is the same reasons we have Trump as a real presidential candidate. There has been a resistant swing of the pendulum. Whenever a group of privileged people lose even an iota of that privilege, it can feel like opression. Just like how Christian's truly feel oppressed, and feel there is a war on Christmas. It's not an easy transition, and can cause a lot of reflexive animosity.
