Nothing teaches them, nothing. That somebody can seriously write this sort of thing in 2018 is truly insane:
We are in the midst of an intense partisan and ideological battle over culture and identity; the Democrats aren’t backing down or moving to the center on these issues; and politicians who want to lead in either party will probably have to take strong, clear stances on matters of gender and race.
Identity has lost them every election since forever, yet they want more of it. They’ve been taking stances on absolutely nothing whatsoever but gender and race. The strong, clear stance they take is that neither is real yet both define everything because of evil racists and sexists. And because choice is sacred for everybody but evil sexists and racists. This form of pouty consumerism is not attracting voters, yet the idiots keep promoting it with fanatical dedication.
