Gilan Republic:We all know of the Azerbaijan separatist movements, even ones for Baluch and Arabs. If shomalis don't like Persians, show me one separatist movement they have currently going.
Also I have a villa in both Gilan and Mazandaran, I go there at least once a year, many times more. They are as nationalistic Iranians as you can find. If you mention this stuff in areas of northern Iran they will bash your head in.
