Why do muslims rise up against their dictators who are only anti islamic?

I believe you need to study restudy about these events. I know a lot about the Islamic Revolution in Iran. After the fall of the Shah (who was a moderate Muslim), Ruhollah Khomeini took leadership but mass anarchy has already taken hold of the country. Ruhollah Khomeini decided to blend Islamic law with democracy to create the Islamic Republic of Iran. I do agree Muhammad Ahamadinajad is not the poster child for Iran or Islam in general. Iran does need a strong anti-American leader to combat all the rivals in the Middle East and North East Africa. The Egyptian leader is a Muslim and he is also a dictator. I guarantee many people would protest against a government who is a dictator despite the leaders views.
