Ahh yes Florida, please teach me how slavery was such a beneficial thing for my race.
I’m sure the millions of slaves that were forced to work in fields without pay, murdered, raped, and were threatened just for wanting equal rights would agree with you.
In all seriousness European expansionism had more to do with nature and the domesticated animals than anything else. Anyone that thinks race had anything to do with European success is wrong.
Race had nothing to do with it? They were considered animals because of the color of their skin. Where's all the millions of white European slaves that were stacked on boats like cattle?
If you're arguing from an environmental determinist POV like I assume @YoBuckStopsHere is, then the racism is a post-facto rationalization of the global dominance that Europeans stumbled into as a result of their geography, climate, and local fauna. I don't think he meant it as an excuse for racism, he just didn't adequately summarize the thesis of Guns, Germs, and Steel before flippantly referring to it.
Guns, Germs, and Steel is pretty widely derided by actual historians and anthropologists, so I wouldn't go putting a lot of weight on that particular book.
Personally I think the criticisms are valid if a bit overstated. Diamond perhaps didn't qualify his claims adequately and purported to explain more than he actually could. However, it's certainly worth considering the effect that environment has on societies. I think if you want to argue that European societies broadly had agency in their exploitation of the world, you have to explain how you would expect them to overcome millennia of violence and greed, develop guns and transcontinental sailing ships, then look at Asia and Africa and say "nah, let's leave them alone". So, individuals certainly had agency in whether or not they partook in the rape or bought into the post-facto rationalizations of scientific racism and the like, but societies amalgamate the competing interests of their component parts, and often the worst impulses win out (incidentally, this is the same reason societies "choose" to fail). And then, ask yourself if you think the Han Chinese would have handled it much differently if it had been them instead of the British. Consider the Han Chinese today. People are people, and people are racist.
None of that changes the fact that white people did, in fact, do those things, and in many (all?) cases owe reparations where none have yet been given. Chances are we'll be on to the next atrocious global hegemon long before those reparations ever happen. Maybe we'll figure it out someday.
