What IS a GOOD Muslim?
In my way of thinking, a good Muslim does exactly what the Prophet of Islam did and said during HIS lifetime.
Good MUSLIMS obey what THE PROPHET MOHAMMED INSTRUCTED ALL Muslims to do.
I question if your Muslim friends allowed you to falsely believe that "good Muslims" are pleasing to you and I, non believers, and those the Prophet said they should kill or subjugate.
If my suspicion is correct, methinks you may have experienced, firsthand, what we both have cited on these pages, of Americans being lied to because we want to think the best of people.
Your friends may not be Jihadis, but would they conceal the actions or whereabouts of a RELATIVE or friend who was a Jihadi?
A good Muslim, no matter how you define it, would likely help a fellow Muslim escape discovery or capture by Americans.
And their values and ethics would have no hesitation in helping a Believer escape American law enforcement efforts.
And the desert sands are filled with the bodies of Christians who trusted Muslims who looked trustworthy or sounded sincere.
