Class Politics is superior because it actually has universal appeal; your politics on the other hand conveniently "centers" and makes most important an ever narrowing number of people whom are worthy of State patronage. And at the end of the day that is what you are all about. Of-course you personally are never going to be easily caught saying that, but the politicos you have advocated for do so. After all you swim readily in a politics that considers appealing to say White voters, especially White Male voters as something to raise alarms and suspicions.
The key difference between Idpol and Classpol is the universality of the policies. Universal Health Care helps everyone; Mandatory Pronoun recognition helps next to nobody in terms of numbers and serves merely as a new mechanism for disciplinarians to harass the lower classes like High Priests chastising the uncouth savages for not being uncivilized. Idpol amounts to a politics of "MORE FEMALE DRONE PILOTS *CLAP*" and an obsession with an ever narrower cut of the population and more importantly privileging who matters and who might get patronage from the State based on said metrics. Class politics isn't stingy like that so there is a clear material difference. But that would require one to actually read Marx and use a materialist lens to look at things. Another thing Idpol doesn't actually do.
