Is tolerance intolerant?

[GrandizerII]

Any political world view (read: PC identity politics) that insists on using race as a metric is explicitly racist, and is in the wrong.

Not if it's using that metric in an attempt to minimize/reverse the effects of racism. Based on my personal experience IRL, people who say the sort of stuff you say tend to be racists but don't want to admit to themselves that they are, so they resort to this rationalizing nonsense to make themselves feel better and because they're under the delusion that if they say stuff like this no one could reasonably accuse them of being racist (and thereby feel they can get away with this "subtle" approach to bigotry).
