The moral values are very different in that Islam allows the use of violence to defend itself from those outside the faith and Christianity discourages it.
Some people say the US is a Christian nation...
Indeed.
The United States is, for all practical intents and purposes, a "secularized Christian" nation.
Founded on the principles, philosophy, traditions, history and culture of Christian Europe.
That dominance within the US exists to this day, and is likely to hold true, as far into the future as may be reasonably predicted.
Islam, on the other hand, is a Johnny-Come-Lately knock-off copycat cult with a fetish for war-making and violence, and suppressing womens' rights.
There can be little doubt that great violence and evil have been inflicted upon the world by those professing Christian beliefs.
But when those wrong-doers made war in the name of God, they were doing so in direct
contravention to the teachings of their Founder.
Trouble is, when Islam makes war in the name of God, they do so in
accordance with the teachings of their Founder.
Big difference.
And, unfortunately, Islam has built-in prohibitions against substantive evolution; changes are locked-out, at the foundational level.
It's founder styled himself the last of the prophets, teaching a 'perfect' and un-changeable dogma, not to be tampered with, moving forward.
Consequently, Islam will never experience a desperately-needed Reformation akin to that experienced by Christianity five hundred years ago.
Today, Islam's cultists tend to confuse resurgence in political power in their domain, with willing submission on the part of outsiders, which isn't happening.
Islam lay dormant, politically and militarily, for centuries, in the Age of European Colonialism.
Given the end of WWII, and the dissolution of those colonial empires, Islam has moved to fill the vacuum left by those defunct systems.
Trouble is, what is moving into that vacuum is medieval, inflexible, intolerant, misogynistic, and hopelessly out of touch with modern life.
The present-day so-called 'resurgence' of Islam is largely confined to their own former domains, it is mostly forcibly maintained, and will not last.
You can't keep people down forever in this new age of instantaneous communication and worldwide sharing of ideas.
