This was inevitable.
The more people become aware of the discriminative way of thinkings of the central government and ethnicity, the more they want to assert their rights.
They are fed up with this Aryan/Fars superiority complex and the way Turkic is considered to be uneducated VAHSHI and Arab considered to be SOOSMARKHOOR descendants of barbarians...
You can see the level of ignorance even in some of the posts here, like "what are Arabs doing in Iran?" and in other threads and communities you see things like "Turks of Iran are Aryan but forced to be Turks" as if all Iranians were not forced to be Persian speaking by one tribe of Aryan speaking Persians and as if before Aryans we were wild barbarians without Summer and Akkad!!!
Regardless of history, there are people in Iran, who consider themselves Iranian still (but not for eternity if attitudes remain the same among the biggest ethnicity), are proud to be Turks with their own unique Iranian Azari Turkic identity (ignorants confuse that with Turks of Turkey) and proud Iranian Arabs, Baluchs, Kurds etc.
The only way to ensure Iranian integrity is to RESPECT ethnicities not to SUPPRESS them, be it in the name of Islam or in the name of ultra nationalistic BS.
Once you suppress people they come out with ingenious ways to work around the suppression!
