This is simply not true. ANY attempt by whites to use IDPol in an unapproved way -- that is, any way that doesn't embrace and internalize White Guilt -- will be tied to the furthest unhinged right white supremacists possible and thrown off a cliff. It's not that they refuse, it's that they will NEVER be allowed to.
It's a tactic called Overton Anchoring, or the Frame Game. They tie you to someone outside of the acceptable discourse and you get dragged out of the Overton Window. Since White Supremacy will always, barring some fundamental shift in our culture that would leave us with a civilization and culture that would be literally unrecognizable to current day Westerners, be universally unacceptable, the universal anchor is White Supremacy. White Supremacy will always be absolutely unacceptable to the average person.
The left also uses a tactic where they intentionally pretend there is no difference between White Identitarianism, White Nationalism, and White Supremacy. Again, since Supremacy is out of the Overton Window, this causes the other two to slide out of the window as well.
But as a Youtuber and Twitter Personality named Frame Games Radio once insightfully pointed out, by putting all three of those positions out of the frame -- by playing Frame Games -- they make Minority Identitarianism, Minority Nationalism, and Minority Supremacy artificially more acceptable. This is intentional. This is weaponized IDPol against whites. You can pick whether or not this is Cultural Marxists doing it to destabilize the west, Globalists doing it to push GloboHomo, or just racist people who really fucking HATE whites. Frame Games was jewish, and he thought it was the result of a "long standing cultural wound to the Jewish psyche," or somesuch. Basically, they really do believe they're god's chosen people, and finding out that the disgusting goys could genocide the 6 gorgillion lead them to believe the only way out was to intentionally destroy the non-Israel west.
The problem becomes that the people that are doing this intentionally know when to stop. Your average woke dipshit online doesn't. So instead of using the Frame Games to keep White idPol under control -- again, the only White Identity you're allowed to have is Collective White Guilt that advances Minority Interests, the only cultural aspiration you and your countries can have is that of a life support system for lazy and worthless wogs across the world -- they try and shove everything to the right of Mao and Stalin out of the window, too. This is your "EVERYTHING'S A FUCKING NAZI" stupidity. They know their masters pushing the button is a good thing, so they rush forward and dry hump the button until it stops squeaking.
The only thing that seems to be a light on the horizon is that this tactic is falling apart, partially because of the woke idiots and partially because of Empathy Fatigue. You can only have your empathy weaponized against you so many times before it callouses over. "It's YOUR fault that a bunch of Rich White Kids played pretend Terrorist in Seattle and started killing people and it's YOUR fault a bunch of ignorant niggers burned down their own city, now pay up whitey" works. ONCE. Maybe TWICE. But people are rapidly going to stop flinching when they scream Nazi, Racist, Fascist, et cetera. That's why you're seeing them try to make "Boogaloo" a thing.
Words are weapons, and the left is running out of ammo.
