I don't know how you refute so-called extremist ideologies when the so-called extremist's can point to the Koran for justification.
As a non Muslim (Infidel)after having read the Koran, I believe the so-called extremists have the correct interpretation, and the moderates are more interested in getting along in this world, than seeking eternal salvation with Allah, by getting infidel blood on their hands. - Tom
There are only three kinds of Muslims:
1) Murderous jihadists
2) Enablers of murderous jihadists
3) Lapsed Muslims
I pray for the day when only the third kind will exist.
