Who's saying that should happen?
Cofty said that quote. Others have claimed that you Simon do not claim , that all Muslims are evil.
Your above comment seems that you are again making that claim.
Islam the.religion is not united in all it's beliefs. There are some factions who are coolant and are oppressive just like their are christian and jewish sects who have a penchant for forcing their beliefs on others.
Islam, like Christianity, is not a homogenous religion. It is divided into many traditions, the main ones being Sunni, Shi'ite, and Sufi.
A very small, radical, hate-filled, extremist, fundamentalist, terrorist wing does exist. Many of its followers follow a fundamentalist version of Islam called Wahhabi. However, Islam also has a much larger peaceful, moderate wing. Unfortunately, the former seem to capture all the media's attention, while the latter is rarely heard from or even discussed by non-Muslims.
It obvious that no one individual speaks for all Muslims. Islam has no single central human authority, comparable to the pope and Vatican for the Roman Catholic Church, or to various General Assemblies and the Lambeth Conferences for the Anglican Communion. Rather, it is divided into many traditions and schools.
