Would you say that diversity is a core value aspect of the PC culture that the article highlight.
Equality feminism focuses on the basic similarities between men and women, and promote the legal status as equal and undifferentiated for men and women. Activism here focused on reducing gender as a factor in how people treated each other and feminism often merged with humanism.
But then the 1980s and 1990s brought about a new focus in popular feminism on difference feminism, with focus on what they call the essential differences between men and women. In opposition to equality feminism, this view advocates for the celebration of differences, and diversity became a key value of the movement. Polarization also increased on this political area, and here I would insert a claim that there is a direct link of causation here.
I have seen plenty of people who say they are not feminist because they follow the views of equality feminism. They think women should be paid the same for the same work, that humans committing sexual violence should be prosecuted, but at the same time object when people are differentiated based on gender. Women shelter instead of shelters for abuse victims, "mens violence against women" laws instead of domestic crime laws, male/white privilege instead of social economical privilege, female hiring instead of unbiased hiring, and so on.
> All you have to do to hobble a movement is associate its name with some garbage.
Or it could be that the movement changed and not everyone is happy about that.
