If people are testy about the volatile differences on Syria it’s because how they are resolved is critical to the future of the antiwar movement, Palestinian solidarity movement, socialist & progressive activists—all of which are being attacked for massive failings on Syria by pro US-intervention forces.
This is not a platonic issue that can be worked out in a diplomatic venue because it represents the clash of classes, the struggle for democracy, competing visions of what is even going on, & some great big military operations, overt & covert, involving several countries.
It’s unfortunate there is rancor but there is a life & death struggle going on in Syria. The results of that struggle will redound upon the entire Middle East—& not just the Middle East but democratic & antiwar struggles throughout the world. No one will be unaffected by what happens.
