Erdogan is not an a “national extremist”. He’s extremely patriotic, like most Turks. You don’t understand Turkish nationalism. Even someone on the far-left is a nationalist. Devlet Bahçeli is a Nationalist who says extreme things. But it’s just macho bluster. Amusing but not to be taken seriously.
Kurds aren’t oppressed in any way like the Palestinians. Kurds feel oppressed by the image and veneration of Atatúrk and that’s what’s confusing you.
