No, it's important to, as Mao said, properly delineate who's our friends and who's our enemies. Otherwise, your org will do cringey shit like the DSA delegation snubbing the Cuban president and talking to a bunch of traitors working for the CIA instead.

Unless you want your org to be completely isolated from the international community and abandon internationalism, it has to connect and break bread with other orgs throughout the world and perhaps even anti-imperialist governments. While the DSA shit the bed with regards to Cuba, I think the DSA also send a delegation to Venezuela where they met Maduro. Obviously, Maduro isn't going to meet with a bunch of dipshits who shittalk him by calling him an authoritarian dictator, but by personally meeting with Maduro, they have tacitly (and rightfully) support Maduro and uphold the Bolivarian Revolution.
