Hopefully the "puppet regime" will put a stop to the rampant "jineterismo," especially the exploitation of Cuba's children, that the current regime tacitly endorses and allows to flourish to the point where it ought to raise eyebrows when some foreign guy (especially older, uglier, and Canadian) simping for the regime also makes a big show of how often they've been to Cuba and how much they "enjoyed" it, just as it would raise eyebrows if they disclosed that they frequented (and loved) Thailand.
This is the same Cuba that sent forty thousand mercenaries to kill Ukrainians in the furtherance of Russia's war effort, is openly allied with both Russia and China, and has a well-documented history of willingly serving (in exchange for oil or other assistance) as a platform for hosting foreign military and intelligence assets hostile to the US, including just recently with Havana Syndrome--and it's a mere 90 miles from Florida. And you seriously don't understand why the US wants this regime gone, for good?
And that isn't even to speak about its rampant human rights abuses.
To understand fully, consider the South-Florida Cuban, anti-Castro culture of which Rubio is a part, from which he surely feels social and electoral pressure, and to the other members of which he surely owes many favors.
This is what any anti-intellectual perceives about the other side of the conflict: monstrous brute, having no other means to enforce his power except through force. In fact, this attitude reflects primarily his own psycho-epistemology.
