I don't wanna laugh and I don't know you but you sound extremely islamophobic. You're literally describing like .0001% of an entire population. The fact that you question the existence of moderate non extremists means your views are super skewed.
If you want to learn more, go research Wahhabism. They are likely what you imagine when you think of muslims but 99.999% of muslims are not like this. This is like calling every Christian a member of the KKK.
