All of this is part of the Left's move to gradually destroy the concept of the individual as an individual, reducing everyone to groups or categories that they define. The ultimate goal, in one word, is dehumanization.
First, the moral polarity of all groups is defined and fixed by the Left. This means the morality of individuals making up a group is likewise fixed (example: blacks are incapable of racism; whites are guilty of racism by virtue of being white). This mindset makes it easy to dismiss any individual who disagrees with you (as can be seen on TOL with Artie Brain and others).
The obverse is true: since the Leftist knows he belongs to the correct group, he has the right to be offended for simply being disagreed with while he himself owes no respect whatsoever to a member of a designated enemy group. As human individuals with their own thoughts, feelings and beliefs, those others do not exist. They are only the extension of their group. If his group is good, he's good. If his group is bad, he can't NOT be bad (though most individual Leftists can't pull of the degree of doublethink required to ignore their own individuality, and so end up utter hypocrites -- demanding to be taken seriously as individuals while dismissing/dehumanizing as BADGROUP anyone who disagrees). That's dehumanization.
Second, it's much easier to be an absolutist this way, especially when they've gained political power. Leftists are free to selectively dismiss or enforce, reward or punish individual acts based on the group they've put a person into. For political purposes individuals can have no individual identity; they can have only that which the Left allows their group to collectively have.
So if a favored group is to receive rights that they do not (yet) possess by law, it is made to happen (perverts allowed into women's rooms) BECAUSE THEY ARE RIGHT BY VIRTUE OF THEIR GROUP. If another group must be denied rights, it's easy to issue blanket denials to everyone within that group (example: leftists denying private property rights by proudly destroying "enemy" campaign signs) because you have dehumanized everyone within that group. YOUR group, in everyday practice, maintains individual rights because you are in the correct group. THEIR group is bad and so people in that group cannot be allowed to have the rights you have. More dehumanization.
Third, once one learns to view everyone according to groups, it only makes sense to assign group virtue and group guilt. The world is so much easier to comprehend -- and control -- without the tedious, messy variances of billions of unique individuals to deal with.
When someone who doesn't quite fit the assigned grouping comes along (a leftist who "goes off the reservation" or a black person for Trump), the Leftist at first cannot process what happened. It violates programming. Inevitably, the person who left is simply reclassified as BADGROUP. And since a GOODGROUP person cannot also belong to BADGROUP, the person who left was therefore never GOODGROUP to begin with ("Uncle Tom," "not authentically black," etc). Even more dehumanization.
All of this is intended to destroy the concept of the individual as an individual. Once everyone has been mass pigeonholed into positive or negative categories, you've dehumanized them. That makes them very easy to marginalize, ignore or eliminate.
It also makes it much easier to mobilize GOODGROUPS to violent action against other targeted BADGROUPS. By appealing to them as inviduals? No. By appealing to them according to the group identity you labeled them with.
It's already happened elsewhere. It is happening elsewhere now. Don't think it can't happen here. It's already is.
