The problem with the far right in organisations is in the link I recently supplied, which I then used a representative quote to explicitly express in #13,418. And I'm far from the first or only person to make that point.
As far as I can tell, your argument seems to be that because institutional racism was not specifically designed into organisations by the far right upon the founding of those organisations, therefore the far right do not cause institutional racism. Which makes about as much sense as arguing that the Nazis didn't cause any antisemitism because the Romans started it.
