I read his manifesto, it of course focused on immigration and race mixing but he also talked about corporate destruction of the environment and automation leaving people jobless.
He talked about corporations taking over the government which leads to more immigration since there's more of a market and cheaper wages but he instead directs his anger at the immigrants. If corporations are going to implement unfair trade deals via the government and do constant tax cuts that sends the majority of the wealth upward then the solution isn't to turn your anger on the powerless.
Right-wingers tend to stick to hierarchies and authority figures, whether it's the military, police force, organized religion, the corporations, and also the traditional family structure. The reaction is rarely to question, protest, or fight people in power, it's usually kicking down. There is for sure a big problem with our government not functioning democratically and only serving those in power, the answer isn't to fight with each other or people below us over the scraps, this is where things like general strikes should be used, which requires not dividing each other.
