The divorce of any kind of supernatural authority from either National Socialism (usually shortened to simply “Nazi”) or International Socialism (commonly called “Communism”) is the major downfall of both.
Islam, on the other hand, a very crude and primitive form of socialism (from BEFORE Karl Marx), first put into place their version of a supernatural being, that was OK with applying draconian threats on the lives and beings of it subjects, to get them to comply with directives that the common good was to be shared by all its adherents. Then some language about killing off all the unbelievers, or enslavement of those who were too chicken to resist, and vague promises of a place in Paradise where females outnumbered valiant defenders by a ratio of 72 to one, for the warriors who would “spread the faith” and die in the effort.
As a result, Islam is ranked among the more efficient ideologies in dispatch of the “useless” members of humanity, that do not accept the anti-capitalist, total conformity of the power of a powerful central authority.
Only the sweep of the “Golden Horde” of Mongolians across most of Asia to the Middle East and even into Europe, was more bloodthirsty and rapacious, even, for a while, taming the Islamic barbarians, until much of the “Golden Horde” itself adopted Islam, but only as a working arrangement, not as a guiding principle. Tax collection was much simpler after that.
Islam is a war plan. Restrict Muslim immigration and confront Sharia law.
