Whatever the word "Islam" means, all things evolve, some slower than others, and the more violent domineering religions tend to become enlightened at some point. Contact with more existing enlightened religions must be a source of influence as well as conflict. One might expect Islam to become less extreme and less violent quicker than most, now the world is more easily travelled and contact with more moderate religions more common.
War occurs between nations, or in the case of civil war within one nation, not groups. It's use as a description is incorrect here, and simply serves to justify creating/reinforcing an 'us and them' attitude.
For sure there are extreme Muslims, but I can not see how anyone can justify that the majority of Muslims in western society is anything like as extreme as those few who commit atrocities. Where one can stop the indoctrination of violence, and hating western values, folk inevitable grow up to be much more reasonable.
One thing clearly needing to be tackled is the lack of genuine integration into society, and some's lack of acceptance of the values of the country they live in. For example, ghettos should be avoided; it is easier to think poorly of others in society if one does not mix and learn of them as individuals. Plus there needs to be more checking that poisonous beliefs and creeds are not passed on in special schools under the guise of religious teaching. But it is for society to ensure happens. Individuals will just carry on as they knew when growing up and the issue thus remains.
I do not expect everyone to believe exactly the same thing as everyone else, there will always be differences of opinion; but I reject one can simply group all of a religion into the same mindset. Every group has a range of opinions.
And to be honest I'm unsure what is being suggested is done to all Muslims anyway. There just seems to be the suggestion that they are all the same, evil people, and it's not right, we should do something about it.
