Communism, Fascism, Nazism, and Religious Fundamentalism are as utopian as the classical Idea of Progress, which is most strongly reified by Western science and liberal democracy. All four illiberal ideologies firmly espouse a linear view of history: Man progresses by accumulating knowledge and wealth and by constructing ever-improving polities. Similarly, the classical, all-encompassing, idea of progress is perceived to be a "Law of Nature" with human jurisprudence and institutions as both its manifestations and descriptions. Thus, all ideas of progress are pseudo-scientific.
Still, there are some important distinctions between Communism, Fascism, Nazism, and Religious Fundamentalism, on the one hand, and Western liberalism, on the other hand:
All four totalitarian ideologies regard individual tragedies and sacrifices as the inevitable lubricant of the inexorable March Forward of the species. Yet, they redefine "humanity" (who is human) to exclude large groups of people. Communism embraces the Working Class (Proletariat) but not the Bourgeoisie, Nazism promotes one Volk but denigrates and annihilates others, Fascism bows to the Collective but viciously persecutes dissidents, Religious Fundamentalism posits a chasm between believers and infidels.
In these four intolerant ideologies, the exclusion of certain reviled groups of people is both a prerequisite for the operation of the "Natural Law of Progress" and an integral part of its motion forward. The moral and spiritual obligation of "real" Man to future generations is to "unburden" the Law, to make it possible for it to operate smoothly and in optimal conditions, with all hindrances (read: undesirables) removed (read: murdered).
All four ideologies subvert modernity (in other words, Progress itself) by using its products (technology) to exclude and kill "outsiders", all in the name of servicing "real" humanity and bettering its lot.
But liberal democracy has been intermittently guilty of the same sin. The same deranged logic extends to the construction and maintenance of nuclear weapons by countries like the USA, the UK, France, and Israel: they are intended to protect "good" humanity against "bad" people (e.g., Communists during the Cold war, Arabs, or failed states such as Iran). Even global warming is a symptom of such exclusionary thinking: the rich feel that they have the right to tax the "lesser" poor by polluting our common planet and by disproportionately exhausting its resources.
The fact is that, at least since the 1920s, the very existence of Mankind is being recurrently threatened by exclusionary ideas of progress. Even Colonialism, which predated modern ideologies, was inclusive and sought to "improve" the Natives" and "bring them to the White Man's level" by assimilating or incorporating them in the culture and society of the colonial power. This was the celebrated (and then decried) "White Man's Burden". That we no longer accept our common fate and the need to collaborate to improve our lot is nothing short of suicidal.
