Multiculturalism and political correctness are two of the fundamental pseudo-intellectual, quasi-religious tenets-- along with a third: radical environmentalism--that have been widely disseminated by intellectuals unable to abandon socialism even after its crushing failures in the 20th century. These tenets have been slowly, but relentlessly absorbed at all levels of Western culture in the last decade or so--but primarily since the end of the Cold War.
They have been at the forefront of attempts by leading academics and academic institutions to rewrite most of history and undo thousands of years of Western cultural advancement. And further, as the culture has been completely saturated with this toxic brew, any attempt to question the tenets' validity or to contest their value is met with hysterical accusations of racism, sexism, homophobia, Islamophobia, imperialism, bigotry, or--worse of all --intolerance or insensitivity.
It just so happens, that these tenets represent three of the four pillars that are the foundation of an evolving epistemological, ethical and political strategy that the socialist remnants in the world have developed and are using to prevent their ideology from entering the dustbin of history.
And, what is most interesting is that, even as they encourage and enable Islam with the first three pillars; the Islamofascists are aiding and abetting them by using the fourth pillar- Terrorism.
Observe how easily Islam has been able to subvert key Western values--such as freedom of speech and expression--with a degree of invincibility and outraged virtue, capitalizing on a tactical opportunity that they have never before had in history. And worse of all, many on the political left--particularly the remnants of utopian socialism-- are aiding and abetting the Islamofascists.
