Look, both 'sides' have been pushing identity politics, and it seems to escalate back and forth. Saying that one side does it but the other doesn't is disingenuous, and saying that it's OK for one side to do it because the other is worse isn't helping the problem. Some of us still remember when racism was wrong simply because it was illogical: the variation of people within a group is far larger than the difference in averages between groups, so it makes no sense to prejudice (literally pre-judge) someone based on their visible attributes. But that cuts both ways. "All men are this," or "all white people are that" displays just as much prejudice, and some small-minded people wanted to continue generalizing about other groups, so hence the rise of identity politics. Push back against all forms of identity politics, or stand by and watch it destroy your country.
