Hmm...I've actually got a lot to say about this but I lack the time at this particular moment. For now I'll just say the leftist is an idiot for basing nothing of his perfect societies on fact(they werne't perfect at all) however he is righ that European colonialism spread a bunch of cruelty and ed up practices around the globe. Did they create all of it? No...but they damn sure spread it to places that didn't have it(at least not in the form they were exporting it) before they got there...
Their two major cultural exports were categorizing races based on intelligence in relation to darkness or lightness of skin, and gender inequality.
You pretty much had to make your women second class citizens if you wanted to the goodies the Europeans could provide. On the one hand you can blame the Europeans for exporting it...on the other hand you can blame everyone that accepted that condition for accepting it.
Oh the leftist is right about one other thing thought not in the way he think he is, the field of anthropology is basically an indoctrination, but what makes the lefty an idiot is that he doesn't realize it's a Marxist indictrination and there are definitely a bunch of ing crazy brainwashed anthropologists, but they are like him. I am pretty sure it is the most liberal field of them all. I think I read somewhere that 30 out of every 31 anthropologists are liberal(and I have met a ton of them that are proud Marxists)....I personally think that's an overly generous ratio...I'd say it's about a thousand to one based on my acquaintances.
Western civilization didn't up Utopia...but it has spread a bunch of stupid ing dividing lines.
