I also do think it's attributed to the working environment you find yourself in. It's quite possible that a lot of these infra-dweebs work in places where reactionary european-americans work and experience the class struggle in a rather monochrome way.

Much like how a lack of exposure to diversity leads mee-maw and pawp-pawp to think every korean-american came from north Korea or literally anyone that speaks Spanish or Portuguese is from Mexico instead of just being normal people like them, I think these infradorks experience something similar and haven't experienced the class struggle beyond their own narrow perspective.
