Except it's not, unless you're so myopic that you're only thinking in geographic terms.
In reality, Muslim immigrant populations in secular Western countries de-spiritualize pretty rapidly relative to populations that stay in Islamic countries, just as do African and South American Christians.
Anyways, why don't you just move to Russia or Poland already? You won't stop being a miserable dolt, but at least you will get to experience white homogeneity.
That "de-spiritualization" is having some pretty rough side effects on the Muslim populations, though.
Jihadism in the West, is usually a reversion to the "old (and most fundamental) way" of doing things, brought about by a gradual de-spiritualization, loss of community, and sense of degeneracy. An identity crisis of the most extreme kind.
There's no real other way to "purify the soul" from mountains of sin, from having been an apostate, a degenerate, except by committing one's self to jihad. Through jihad, one can be forgiven for any transgression committed against Allah, and reach the state of absolution, that would otherwise take a person decades of religious meditation, study and proper behaviour to accomplish. In the past, this pattern of thought was utilized to form a strong warrior class, which would be enabled to partake in "degenerate worldly pleasures", where others wouldn't be able to. Through their acts of violence on behalf of Islam, all of the common sins of rape, murder and pillage, would be forgiven, and their ascension to the paradise ensured, enabling warriors to fight in battle without a regard for their own well-being.
By de-spiritualizing the Muslims, and Westernizing them, and subjecting them to Western perceptions of morality, we are forging a potent generation of jihadists, Islamic warriors, for the coming century. Islam wasn't built to merely "disappear" without a trace. It has its own distinct functions which will ultimately enable its survival in any society, by resorting to brutish violence if necessary.
While peace and harmony form Islam's exterior (under circumstances where its position is not threatened), violence will always lie at its core, because violence is how it was initially brought to the world, and violence is also what ensures that it will stay.
