In our society, in our form of government, the underlying principle is that God has created us all equal and endowed us with unalienable rights that give us precisely the freedom you talk about. In Chrstendom, the principle is one of free will.
The radical Islamics believe in no such thing. They believe that God hjas instructed them to use force and compulsion. Adhere, conform, or die (or be enslaved).
These diverging fundamental, foundational principles to the two societies and how God is viewed being behind those principles is what leads to the plural, free society we have, and what maintains the tribal, tyranical, leader-oriented societies that they try to maintain.
But that is just my opinion.
Which is precisely why we should treat islam in the same manner we treated Nazism, Italian fascism, and Japanese Imperial militarism. Namely by destroying it utterly.
But that's just my opinion.
