Political discussion needn't be a zero-sum game. Providing equivalent examples of bad choices on the right does not nullify arguments against IP and tribalism.
Also note it is somewhat humorous to read the dismissal of IP overreach made using an IP point of departure (Who you are or where you're from does nothing to refute group behavior claims).
This isn't to say one can or should avoid IP entirely, I'm just saying it's being used to quash reasonable debate fairly regularly nowadays, and the data of its increased abuse exists in the real world if you only look for it.
So what is it in your estimation that drives the language of collectivist movements like the alt-right or antifa?
