Conservatives are not upset that they can't use racial slurs they are upset that victimhood culture isn't really about equal rights it about special rights. Unless your a victim you have no input. The left has an issue that they don't believe the rules they want to impose on the on others they brand as racist to be applied to them so it is critical to be in the victim category.
The left is worried that the white men are starting to use the identity politics that the left has so readily embraced. It should scare them, identity politics are at their core racist.
