The PKK are a minority faction of the Kurds and your slander is misdirected. As you know, the YPG are the majority, and they do not share ideology or methodologies. These Marxist-Lennonists are the only force in the region that has sheltered minorities including Christians and Druze. Theirs is a complicated history, and they dont fit nicely into our comfortable Western ideological boxes, but your characterization is just Turkish propaganda.
The only valid part as far as the communist charge would be the Kurds have set up communal agriculture similar to the Israeli Kibbutzes. Such ventures have proven very successful and make sense in the region, but you already know that. Not every conservative jumps at every red flag, especially when its weilded by a Matador serving the real Reds and their dictator friends.
Turkey and Russia are not our friends, and it would be inhuman to leave the brave people who truly defeated ISIS in their hands. Whatever happens, Turkey and their new Red friends will find the YPG much more resilient than the typical Arab mob army.
Rebranding ISIS as Turkish Army, allying with Russia, or smearing the PKK label on all Kurds wont change the moral equation much. The difference is the big players have no monopoly on truth. Those who know, know; and I for one pray constantly for the brave Kurdish fighters who stood virtually alone in their opposition to the worst genocide seen in this century.
The Marxist-Lennist Kurds are being armed by evil outsiders who only want to use them as cannon fodder to destabilize the region.
