Agreed, Isa. Evangelism will crush Islam, because as the Islamic scriptures put it, "truth stands clear from error". Against the truth, Islam has no chance. As was likewise said to come long ago from the mouth of a pious Muslim (one surely much more learned than Muhammad), "were it not for the fear of the government and of shame before men, many would become Christians."
Regarding the "some muslims" idea: Acquaintances I have known who have converted from Islam to Orthodoxy and from Islam to Catholicism have told me that it is pointless to look at 'some' Muslims are doing now, either good or bad. What really matters for pious Muslims, according to these people who have lived in Islam, is actually something similar to what we might look to in Christianity: How did the first generations
of adherents view the religion, especially the parts/passages that now seem contentious (i.e., the ones that Muslims try to explain away in order to make us believe that Islam means "peace")? When you look at that, you see that the early Muslims understood these commands to slay polytheists, to fight the people until "all religion is for Allah" (i.e., until everyone is Muslim), etc. exactly as they appear to be written -- as commands. And when Muhammad apparently said (recorded in one of the collections of "hadeeth") that whoever changes his religion should be killed, they took that
literally, too. They still do.
The philosophizing or de-materializing of these problematic verses and ideas didn't come around until much, much later. These are modern "neo-Muslim" ideas that are foreign to the history and major personalities of Islam. The Islamic "fatuhat" were offensive wars. Islam is still
waging these offensive wars against us, though most have learned to not be quite so explicit about it as bin Laden was...at least not right now.
