Not necessarily. My wife is a member of a Muslim sect that does not interpret the Koran in ways that promote spread via coercion and violence. They do not subscribe to any follow-on books that further entrench intolerance and violence. The teachers in her sect all have very high level science degrees. Instead of sitting in front of the congregation barking out intolerant rules for how they should believe "OR ELSE!", they teach them how to learn about it on their own. They promote using your education for the overall betterment of mankind. One of the teachers is my BIL. He is a PhD physicist that has been involved in super conductor research and radiation therapy related research. They are actually somewhat pacifist and are non-violent.
The only problem is that the government of Iran declared their sect to be illegal and systematically persecute them via the power of the government. As a result, they are spread throughout the western world and not allowed to get their POV out within the Muslim countries.
Curious about your wife's brand of Islam. Rough count - how many are there associated with this sect? You say that Iran has declared your wife's sect illegal. Have other countries declared your wife's sect illegal? If not, why not? Is the sect your wife in strictly Persian?
Are there other sects within Islam that have roughly parallel philosophies? If so, which and where are they primarily located?
How do these numbers stack up against the roughly 1.6 billion muslims in the world today?
