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
Show
Deeply unserious people
No actually I think the entire DSA org should disband if they can't keep their members from denouncing people they're on a diplomatic mission to visit, or meeting with anti-communist opposition groups, without being censured or suspended.
If members aren't accountable for anything they do even while on an official visit, then no one is going to trust them in the slightest.
This is why DSA libs eventually get themselves disinvited from the planning (and sometimes participation) of actions. They reveal that they cannot be trusted.
