Things need to be properly named. Political confusion starts with terminology confusion. Islamism implies some sort of political and social plan for Muslim people. In that classification, we find different categories. Legalist ones, traditional ones and revolutionary ones. Some of them are revolutionary but are non-violent, others are extremely violent. There are also the ones we call the literalists, like the Egyptian party Hizb al-Nour that used to be against democracy and now is getting into the political game.
