The problem with that is that, just as in our foreign policies, it assumes an 18th century liberal European mind set and traditional European definitions of religion.
The problem today, one that AdamSmithWasRight faces just as the rest of us do, it that Islam itself is literally the opposite of those core beliefs.
Islam is a construct that intends secular bodies merely to administer religious dictate. It should be no surprise that those dictates may change from generation to generation:
Not many guitars in Catholic services a half century ago.
Not many homicide bombers wandering our subways only fifteen years ago.
What ASWR and any like him (her?) must face up to is that today's OFICIAL islamic direction is expansionist, violent, and well tuned to known western weaknesses. He appears to face up to the FACT that overseas muslims have failed utterly to present a counter argument based on their generally better conditions outside of muslim states than within them - and the absolute lunacy in believing that things would be better in an islamified west.
He may well also have to face the fact that his co-religionists might well seek to punish him for it.
It seems clear from Taxi driver's denial of services, from demands for the 'right' to go masked (when that is not even a part of islamic writ), and the insta-mob politics of European muslims, that they are now re-writing their creed to support violelnt expansion.
It does seem true that muslims intend to be muslims first and Americans (etc.) only when the other side has been subdued. That attitude has been honed on over fifty years of UN/NGO/PC acquiescence toward violence and deceit and without change I don't see how you mend fences.
Even longer than that. Islam has been brushing the dust off itself since the defeat of the ottoman empire. They mean to take it all back, and then some.
