There are some Muslims who have turned to Jesus, so Muslims are redeemable. But, it is a difficult process as it is with any strong cult, especially one which controls vast swaths of earthly real estate and cultures.
The problem is getting through the brainwashing, threats and cultural bondage imposed on it's adherents. It is an easy religion to enter but a very difficult religion to leave. It can cost you your life as well as complete ostracism from all your family and society in general. The blindness of Satan's deception is exceedingly strong in this theology as it encompasses all major spheres of human life - social, familial, theological, political, judicial.
The final arbiter of the sword is never far from the hands of Muslim believers and fanatics.
What you say is true.
I can't see how we can defend ourselves against the issue of Islam until we have a clear plan of action...
Do we undertake to deprogram muslims with a massive campaign while at the same time waging physical war against its soldiers or do we do what we are doing now and that is ultimately putting out fires...
It seems to me that right now we are fighting a battle but losing the war.
