the term "idpol" is a slur!

 When you come across the term “idpol” see it for what it really means. 

It's a portmanteau of “Identity” and “Politics”. But its a very particular Identity and Politics the term is condemning. Namely “The Personal Is Political”. A statement by Carol Hanisch (1970), writing about second wave feminism, and often considered the defining trait of 3rd wave. 

Politics as a term means nothing more than “Social Power”.

The users of the term “idpol” are expressly saying that they dont want some peoples identities in power. Even though they won't say it in mixed company, the Identities they want excluded is explicitly clear. By using that term they are saying that allowing power to consider any outsider, its taken away from the “right” purpose of politics. Politics is for Rich White Cis Hetro Men of a Select heritage, bloodline, cast, and family. The longer they are allowed to go the more they would like to exclude from their permitted list.
In politics, we call that thinking “fascism”, although its usually not openly called that until violence and force are used to support the ideas. 

If someone starts using that term in any group you’re in, I advise: Quickly and clearly have them define exactly who, exactly what identities they are saying is muddying up their pure white politics. Don’t let them try and say “it means politics of personal identity”, because, All politics is of personal identity. Which exactly are the Identities they think are not valid enough to be part of the political discussion. Because these people want to try and get you to agree with their bigotry and hate, but they know if they say it outright, most people will not even entertain their ideas, so they want to sneak it in they want to get you to agree with all their hate in broad “Other People” before they can then try and slowly introduce the identities they include in that group.
I won't allow any other topic to continue until the offender will openly retract their hate words. The same way I respond when someone drops any other slur into conversation. We now live in a time where you need to be Anti-racist. Just being “non-racist” isn't enough anymore. When you allow bigotry to go unchallenged, you are supporting those who use that racism to further harm others. The Personal Is Political, and personal attacks are political moves. The term “idpol” is a bigoted and racist slur hidden in conversational tones. But just like calling “liquorice kids” “N***er babies” is racist, and you should call out anyone who tries to act like its ok. Because letting people say it is agreeing that you don't care about how it makes black people feel, you're agreeing  they don't matter.
