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
But there is a second aspect of the crisis which we did not focus on during this delegation: a crisis of political legitimacy. Cuba’s government is a regime where decision-making power rests in the hands of the Central Committee of the PCC (the only legal political party) alongside its bureaucracy while the elected legislature is a disempowered rubber-stamp committee. Legally recognized mass organizations we met with on this delegation, like the Committees for the Defense of the Revolution, Federation of Cuban Women, and the Workers’ Central Union of Cuba, are loyal to the bureaucracy, while independent political organizing is repressed.
This is from that "comrade" who skipped the meeting with the president. Tells you all you need to know about them. The DSA didn't focus on this "second aspect" but she really wanted to hijack the trip and make it about this instead of the blockade, so she pulled some immature stunt to get attention for her idealist bullshit
