Part of the issue is lumping in the populace, as if they can not be educated or join in the revolutionary cause. Even Fidel Castro, said and I quote “In Cuba we have never cultivated hatred against the American people or blamed them for the aggressions perpetrated by the governments of that country. That would have run contrary to our political doctrines and our internationalist conscience, both well-proven throughout many years, and increasingly rooted in our ideas.” We are communists, sure we struggle aganst the capitalist class, and aganst imperalism, but we should not stoop so low as to condemn entire groups of people just because of where they are from. To quote Castro once more "“The Revolution’s work is not limited to material work, it has worked on people’s consciousness, on their soul, preparing the human being as the human being of tomorrow, of the future, should be, and fighting against the lies, fighting against the dirtiest and gross propaganda, fighting against blockade and fighting against the harassment that tries to weaken the Revolution, to weaken its morale, its consciousness”. we cannot do that if we demonize groups of people for traits they cannot control.
