Again and again we see the attempts at destabilizing regional countries.
Iran is a country of multiple ethnicities. What's the best way to destroy Iran? Same way they destroyed every other country in the region, by talking about sects & ethnicities & groups & clans until the body eats itself and all that remains are white American boots on the ground, walking comfortable among the ruins.
Iranian Kurd are as Iranian as the rest of the country. One day propagandists are talking about Kurds persecution, then another day its about Azaris, or about Arabs, or about Lors, or about Baluchis, or about Sunnis but if they combine all these "minorities', you get the complete IRAN.
This is an incident in a small town regarding an angry population demanding justice for an alleged rape of a young girl. The same anger could have happened in any other Iranian city.
Any Iranian is 100% Iranian, no matter what their "ethnicity" is. We have no patience for your European style race lines.
The current Tehran mayor (and mayor for many years, constantly getting re-elected) can be said to be Kurdish (although to me, he is just Iranian).
