First, not all revolutions end up like Syria. Relatively bloodless coups are common, and even many civil wars with fighting are much less bloody and disruptive than the Syrian civil war - the US war of independence might be one example.
The second is simply that if no revolution is justifiable, there's nothing to make a despotic monarch give any attention to the needs of their people - as the people will 'sensibly' not revolt anyway. So on the one hand Germans shouldn't resist the holocaust, or Cambodians the killing fields, and on the other you get figures like Charles I and various French Louis' making tensions in their countries far worse because they believe their position is secure. Neither is a template for a happy society.
>"All civil wars are bad" produces logical contradictions such as both the rise and the fall of the Soviet Union were bad.
The fall of the Soviet Union didn't occasion a Civil War.
they can both be bad, it's just that "the bad" is different in each case.
The PKK is the main political force behind Rojava or the Democratic Federation of Northern Syria, a group of self governing cantons in Syria. These are the first significant truly democratic and secular developments in the region in a long time. It is also a bold experiment towards tolerance(Rojava is comprised of Kurds, Arabs, Assyrians, Syrian Turkmen and Yazidis as equal members) and gender equality,
The movement has strong anarchistic tendencies, and the PKKs leader Abdullah Öcalan(currently imprisoned in Turkey) is heavily influenced by American anarchist Murray Bookchin(though he later preferred not to use the term).
There is no central government, and it is a union of self governing cantons. The cantons are collectively managed through Athenian style direct democracy, with strong participation of all ethnic groups and women. The YPJ is the purely female counterpart to the YPG.
If Rojava succeeds, it could be an outcome exponentially better than the Ba'athist/Islamic Nationalist status quo. Even if ends up failing, it is a symbol of hope to me, hope that we as a species can radically rethink social relations, like the French Revolution, the Paris Commune, or Catalonia during the Spanish Civil War.
