We aren't talking about true sections of our society. Revolution should not even be an issue for illegal aliens.
Neither should openly marching to protest the infringement of rights they actually don't have (nor deserve, being uninvited invaders). If they can march without fear of authority entertaining that mass delusion why shouldn't they consider more extreme measures?
We're talking about a group of people who've been herded here by a bad government that filled their limited educations with lies about how all their troubles are somehow our fault. And don't forget the Aztlan fairy tale so many of them take for granted. Sprinkle liberally with Che' and socialism and let simmer in discontent.
