The ideology of race is used to justify imperialism, wars, and the racial division of labor.
Racism promotes nationalism on the basis of ethnic identity.
This only strengthens enthusiasm for participation in national armies. Those people within the Working Class who hold racist views are puppets of the rich. Contrary to popular belief, racist ideology is actually derived from the Middle and Upper Classes where the real power to split and weaken the lower classes lies. This division occurs through discrimination in social services, education, immigration, and working conditions. Most of this racist filth is received by the majority of the population, which is, of course, not in power.
