Some say the election of Donald Trump is in part due to the backlash against the intolerance of the left. He definitely does not say things to be "politically correct".
(For anyone who hasn't seen the acronym before.)
It is similar to policies that made access to home ownership easier (for some) because having a mortgage (and equity) is implicit buy into the system which lowers the likelihood that you’ll fight against it.
Those without equity have nothing to lose.
"Good" discrimination, a worldview that requires racial essentialism and stereotypes.
Reduce everyone to their immutable attributes and tailor your behavior accordingly.
Since in the minds of social justice people, one group is unconditionally placed below another group (think of the vocabulary they use when they say "the work is never done"), we must actively discriminate to fix things.
