I think Muslims are just a distraction. And in some respects, a good thing: They have harsher views against degeneracy than most Christians nowadays.
The real problem is within. The real demons are those in the churches softening the message of Christ, or even outright denying Christ and teaching skeptical outlooks on scripture (whether written or direct from the pulpit). Along with that, they emphasize forgiveness before repentance, giving a lax view on sin and no sense of taboo in culture. Over time, they keep upping the ante on what is forgiven or "not a sin", to the point that transsexuals, abortionists, adulterers, and queers are the very ministers.
It's true that Christianity is more merciful than the likes of Islam, but to say it's not harsh to the unrepentant is a lie. And the world - chiefly the West - is now suffering because of this soft attitude. Each little "exception" made contributes to an avalanche with no escape.
In some ways, I think God has allowed Muslims to infiltrate. For if people don't want to act wisely by learning the gentle way of Christ, then he will give them up to monsters and they will all have to learn the hard way. Either way, you learn. Take the easy path or suffer the rape of an inbred psychotic mob to force you out of degeneracy.
But the people who put you in this predicament are your own leaders and teachers and preachers and publishers. These are the true Satanic forces you should have been worried about all along. If people even had an ounce of outrage against them as they do Muslims, then society would be safe. If you had thwarted them to begin with, you wouldn't have Muslims either.
