They've also appropriated the 'there is no absolute' truth idea, that is used to try to make people understand differing perceptions. It was used to try get people to accept different view points, basically something that liberals and hippies came up with in the 60s. Now it's been appropriate to further the post-truth politics. If there is no truth, why not always lie.
The real frustrating part is that this conflict was totally unnecessary. Yes listening to feminists and black people can sometimes by hard to white males, it sometimes appears unfair and as if they want to 'reverse' the world. But overall, that's not the aim of these movements. And we (the white males) should really just give them the benefit of the doubt. We should listen. It hurts, but the conflict hurts them more.
Instead, some of the people in a traditional position of privilege have successfully turned around the conversation, into "no, you should listen to us".
And now this group of people, many of whom were traditionally democrats (even may have voted for Obama), now voted for Trump. They are the swing vote.
