Identity politics are a game that can probably only be eschewed by the people who are going to lose.
Pointing out that identity politics is unfair and unreasonable to the people who play/live by those rules just means that they automatically win.
An example of this would be expecting parent not to prefer their child over other children in parent teacher conferences or school administrative meetings. People side with the group they identify with and maybe they’re obligated to do so (maybe not) absent violations of truth, goodness, and beauty. But it seems that many of the Americans who reject identity politics as tool for political power or ethical reasoning still watch various versions of sports and have deep emotional attachments to those teams. They also tend to show a lot of loyalty to their alma mater.
