The final goal of Islam is a worldwide Caliphate ruled by Sharia. The world that Islam’s followers dream of is a planet ordered after the wishes of Allah and his prophet. In such a world there is no Free Speech since the slightest criticism of the system is to be punished by death.
There is not even Freedom of Thought, since everybody has to believe in Allah and Mohammed as his prophet, pray five times a day, eat halal, and kill family members and others flinching from the Islamic rules. According to Sharia, women are effectively the property of their male family members and men are allowed to have four wives and beat them all.
