Which civilizations ended because of homosexuality? More interestingly, which epoch?
Spengler's foil was primarily the Greco-Roman civilization. But he touched on others as well, Egyptian, Babylonian. And if you're going to paraphrase my post, Tonnington., please do it correctly. The widespread collapse of the founding morality, which is always religiously based (as is the founding inspiration for that civilization), and which is unarguably Judeo/Christian for the West has always been coincidental with the decline of that civilization.
His thesis went well beyond morality.. to science, technology and economy, to the Arts, to forms of governance, which always increasingly were centred in self contained, remote cliques (does it remind you of our courts), to primary social components, family, schools and community. All went through periods of intense confusion and rapid disorganization. Although you could rightly argue that homosexuality has always existed in all societies, it's validation and legitimization ONLY appeared during times of precipitous decline. A vibrant culture bound by its founding religion.. has NEVER accepted homosexuality as moral or natural.. in any Civilization in history. It is only when those religions are in decay, that suddenly this specific phenomenon appears in ever more credible forms. I have conceded that i don't know if it a symptom or propellant.. but my guess is a bit of both. And it is with us in spades now.
An epoch is defined as a span of time marked by specific characteristics, which makes it a subset of Civilizations, but take your choice of microcosms of history. A good one is the Nazi era in Germany. In the wake of their devastating loss in WW1, hyperinflation.. the national socialists were infused with both homosexual cults and the occult, and aggressively denied, in fact persecuted German faith based groups.. Jews and Christians.. and of course it died in flames. What we are dealing with now, is not limited to a specific region, or circumstances.. it something that is pervasive throughout the West.. civilizational is scope. .
And as far as lag time, jim, the end of the Greco Roman civilization likely occurred over a period of a couple of hundred years.. before the Barbarians were at the Gate. But technology, and especially communication, has sped things up dramatically in the modern era. Some would say the barbarians are already at our gate, and it is only about 3 or 4 decades since the jaws of collapse have started to bite with avengeance.
