What many westerners fail to realize about Islam is that it is NOT just a religion. It is a sociological/economic/political philosophy using "religion" (and I use that word "religion" with the broadest of definitions) bent upon World domination. Convert or die! That is their message.
The sooner the non-Muslim world accepts that the sooner we can defeat destroy this insidious philosophy.
And I for one don't think you are being pessimistic. I think you have a firm grip on reality. There is no other major philosophy that teaches a quick way to heaven/nirvana is to kill "non-believers". Islam at it's core is evil and bent upon our destruction.
The best defense is a swift and overwhelming OFFENSE!
But what is most bothersome is that, because of the relativism that is the new civic religion of the USA, we seem to manifest to the Muslims of the world a lack of will to defend ourselves.
That simply emboldens them.
What about socialism as practised by the former Soviet Union, China, North Korea and Cuba?
