No one is more pissed off about these guys than the Kurds, you look at the interviews the media has with them and independent journalists and they hate ISIS with a passion one was saying "They aren't human, they're monsters" because of how they tricked this guys daughter and messed around with them when they were trying to escape ISIS controlled territory.

These guys have had a bone to pick with the Suni Arabs and the like in particular since the days of the Ottomon empire.
