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
Diaz Canel was a fierce supporter of LGBT+ rights, he send doctor missions during the covid pandemic to help other countries like Mexico and Italy, continue support of palestine, he is not Biden, he responded to their criticism and hosted the DSA in Cuba, at least they should have meet the guy
