Which stereotypes are you talking about? Some of them are easily explainable but you need to say which ones they are. In general though, people stereotype Muslims because they are believed to live by a codified set of rules as laid down in the Qu'ran. Unfortunately people forget that not every Muslim is that devout. People need to learn to seperate Islam, the Qu'ran and Muslims. Not every Muslim around the world believes we should be living in a Caliphate, not every Muslim believes in the "Territory of Islam" and "Territory of War" ideology (sorry, the Arabic term has slipped my mind), not every Muslim believes that women are inferior. It all depends on how devout a particular Muslim is. Some follow the faith, others follow the word and political/social ideologies that are laid down in the Qu'ran.
