By a few radical extremists. Do you really think that ISIS speaks for all of Islam and all Muslims?
YES.
It does to a degree. And its just my opinion below right or wrong. This is how an atheist views it.
We need to set this up in context, because it is a problem within islam, and it is NOT an isolated few that embarrass the religion. It is a huge percentage.
WE have a degree of liberal and moderate religions. Right or wrong I'm going to show you an accurate scale of radicalism.
Lest say the most liberal are typical Jews not the orthodox. Population of these people are very small from typical to radical.
Next is Christianity the largest, and we have some fanaticism but it is for the most part non violent.
With islam the fanaticism is required and practiced daily. Imagine if being a YEC was required to be a Christian, that is a similar level of fundamentalism, but not by the minority.
It is required by every last one.
As an atheist, I view this as people living different degrees of mythology as being true. And of all Abrahamic traditions, to me islam lives the most mythology by far.
No amount of facts or evidence can change their mind on core objects of faith, to me when people refuse this much reality, it brings up the element of "how dangerous can faith be" ?
MY point is we have a few radical Jews, we have a lot of radical non violent Christians, and we have all Muslims who are extreme and radical in their faith.
