Yean, sure, sometimes it is like they train us to dislike those authors. But as a spaniard, had you ever heard of someone who was recommended/required to read Maquiavelo? Maybe some weird philosophy teacher? Even more, do you know a lot of people that knows even the name of the book "El Príncipe", and not just "Maquiavelo: el fin justifica los medios", and that's it?
