Honestly its rude to be invited by a country to meet their president who decided to respond to your criticisms of their administration only to not show up and go meet the opposition.
Being invided and then no showing shows complete disregard to basic diplomatic Etiquette since it was a mission to show solidarity against the embargo
Bonus socdems being cringe part 4.5: about another member that didnt show up to the presidential meeting
Deeply unserious people
you cannot in the same breath levy criticisms and refuse to entertain the head of state specifically trying to meet with you to discuss said criticisms. it is petty and chauvinistic and betrays an idea that your aim of criticism is destructive rather than constructive–an attempt to jettison ideologically from the project rather than contribute to it. if they truly wanted to see the communist experiment in Cuba succeed, they would jump at the chance to communicate their ideas with the people currently running it.
Ultra chauvinists like Maria call for debate but they really just want to platform their own ridiculous positions and listen to no one. This is par for the course in what counts as debate among this brand of Trots.
