This is a discredited Guns Germs & Steel tier argument. Europe is actually very resource-poor compared to Africa and China. Africans notably have the same livestock and better surface resources than European Whites. Which is actually part of their problem. You don't need to evolve cognitive talents or advanced social organization to survive in an Edenic paradise in the Tropics. The selection pressures in Africa and in Europe were towards different things, and ultimately we have Eurasians because of those selection pressures.
Not to be that guy, but there's actually at least some truth to the Guns, Germs, & Steel argument even if it does get oversimplified by a lot of people. It's true that Africa had much of the same livestock as Europe and Asia except for the one species that counted the most: Horses.
Horses were one of the biggest reasons why Europeans and Asians more or less "won" the game of civilization in addition to other environmental and evolutionary factors. Keep in mind that the resources in Africa were more abundant than in Europe but are mostly in the harsher interior of the continent where it's extremely difficult to develop a civilization beyond the small tribal level
The "Tropical Eden" is mostly a thing for the coastal and island areas of tropical regions. As you get further inland, the tropics become less "Garden of Eden" and more "Cannibal Holocaust" and that's where the environment really starts to fuck with the development and evolution of human societies.
Tellingly, the only regions of Sub-Saharan Africa that had societies more complex than small tribes were generally in coastal areas and near major trade routes. Ethiopia is a prime example of this, being centered on the eastern coast of Africa and taking part in extensive trade with the Middle East since ancient times.
This argument "White people invented homophobia and that's what made them more successful" is retarded. If Homophobia leads to success, why is homophobia wrong again?
Also, Romans were hella gay and they conquered so much. So, no.
As were the Greeks and the Celts. Fuck, the Celtic peoples were even gayer than the Greeks or the Romans. Even the Germanic peoples tolerated homosexuality up to a point provided you toughed it out and fathered a son as well.
If any people can be credited with inventing homophobia, it's the Jews. The Israelites (of which the Jews were one tribe among twelve) were the first people to truly have a blanket ban on any kind of homosexuality. The Christian concepts of degeneracy are largely derived from the laws found in the Torah.
If you really think about it, Christianity is one of the Torah's three bastard daughters, the others being Islam and Judaism, although you could count atheism as well since atheism probably would not exist if it weren't for the dominance and austerity of Abrahamic monotheism.
The only reason why homosexuality became completely taboo in European society is because of Christianity, a Semitic religion. Yes, Jewish subversion of European White culture is really that old. The Edict of Milan is by far the most successful example of it.
The Church Fathers were more or less the Frankfurt School of the Greco-Roman world if we're being honest with ourselves. (((Traditionalists))) hate hearing that though.
