I support these men and women. Being ISIS is far far worse than whatever YPG is.

If you're curious, the YPG follow an ideology called democratic confederalism. The following quote is from the book by the same name written by Abdullah Ocalan:

The right of self-determination of the peoples includes the right to a state of their own. However, the foundation of a state does not increase the freedom of a people. The system of the United Nations that is based on nation-states has remained inefficient. Mean- while, nation-states have become serious obstacles for any social development. Democratic confederalism is the contrasting paradigm of the oppressed people. Democratic confederalism is a non-state social paradigm. It is not controlled by a state.
