Moderate Muslims and The Great Commission

Why do evangelical Christians way so much time trying to Moderate Muslims to admit that what the radical Muslims are doing is exactly what the Koran tells them to do?

Yes they are Fundamentalists, but those people are not open to discussion or reason.  They are so firm in their beliefs, it is correct or die!

With the Moderate Muslim, you can have a dialogue any chance to witness to them.  Something you will never have with a Radical/Fundamentalist Muslim.

We're not told in Scripture that everyone who hears our message will repent and believe.  Only that we are to preach the Gospel in and out of season.  At one time Jesus had thousands following Him, but after His death, only 120 were in the upper room.  We should not waste so great an opportunity to witness to these people, while spending our time trying to convince them they are wrong.

It is not our job as Christians to judge these people, but to witness and warn them of their error.  They are God's children just like we are.  God is not a respecter of persons, but loves all equally.  Jesus died for all sinners and that includes Muslims.
