Racism, sexism, et al have never been about race or sex or what have you, it has always been about power.
The radical left sees the longstanding paradigm (male, white, straight, in that order) as having committed such wrong in the past that they are "unworthy" of their power, and even equality (forget the science and philosophy, they're bad because of colonialism/slavery/sexism/genocide/name it)
Some men (and some white women) are furious about their eroding privilege, as if they were randomly given front-of-the-line passes at Disneyworld, then arriving to find out that their passes have been disabled or given to people that don't resemble them.
Others see a pendulum of history favoring the paradigm shifting too quickly and lending opportunity to those who hate straight white men, and do not have to be racists or supremacists to acknowledge the danger of overreaction.
Overreaction can be dangerous and chilling to real discussion. Just look at the folks who downvoted you without comment, and we are left to believe that they merely disagree with you.
