Bottom line: authoritarian regimes have a really hard time with criticism, whether they are left or right.
Hitler and Stalin were on different sides of the political spectrum and hated each other with a passion, but to me they seemed exactly the same. They both oppressed and murdered their people, stiffed any dissent and only the insiders and cronies saw any benefits. Unfortunately Argentina along with the US, Russia, China etc seem to be going in that same direction...
