The PKK is what Antifa types would go join when they went to Syria to fight ISIS. I honestly am not a fan of them, but nor am I a fan of trying to partition Syria and inflame conflict in the Middle East yet again.
YPG/YPJ never advocated partition of Syria. They avoided conflict with SAA, only incidents were caused by Iranian forces. In those case US support did fire on them and Kurds protected themselves.
PKK is NOT the same a JPG/YPJ or the SDF.
I know about them all, have followed this for over 4 years. I hold Syrian Kurds in high respect. Their Arab allies were also good allies in the battle against ISIS.
Since liberation from ISIS the cities the SDF liberated are back in local control with representation proportionally along ethnic lines. They have been a resounding success in stability since ISIS is gone. But are a long way from total recovery of what was destroyed by ISIS.
The Antifa types joined the SDF too. They made the Syrian troops roll their eyes. Needles to say, they were not leaders in the battles against ISIS.
Won’t go into detail about that here, but will be glad to discuss it with you.
