It's really sad to see how well the right is brainwashing a new generation of adolescents.

It's generally not brainwashing. Ideas come from Material Conditions, the ideas that are popular in society come from the world around you, not through the Marketplace of Ideas or anything.

Fascism and Socialism/Communism are on the rise in Western Nations because Imperialism, ie Capitalism at its highest stage, is crumbling. Without being a class reductionist, you generally see fascism arising as a link between the petite and the full bourgeoisie against the Proletariat along nationalist lines, as a way to "turn the clock back" to a less decayed point in time.
