The fact nobody talks about is that not only was every culture saddled with religion from which they drew a great many assumptions, but Charles Darwin wrote 'Origin of the Species' in 1859, (only 150 years ago), so before that we genuinely didn't know whether the primitive races we encountered with their loin clothes and unintelligible jigaboo crap were even human or capable of being civilised at all - let alone human.
Just imagine if we came across a lost island of Neanderthals in the CURRENT YEAR and they were too unintelligent to civilise at all. You gotta draw the line somewhere.
After Darwin, since we realised the relationship between monkeys and humans was a thing, people understandably started to consider other races as some kind of "missing link" intermediary. Not how even Darwin's theory works exactly, but you can still easily wind up with subhuman intelligence that makes you question the boundry between animalistic ape and homo sapiens.
All things considered, anything less than exterminating every single one of the more primitive races, was downright enlightened of us in retrospect. So l'm definitely not going to shed a tear over any misunderstandings - especially when there are races with ridiculously low average IQs who are still barely civilised in the CURRENT YEAR.
We have nothing to feel guilty about, save letting them get away with as much as they have due to our own often misguided benevolence.
I often use this example. Imagine super advanced aliens came to Earth in their high tech spaceship.
They start killing us - like a billion people, but after a time realise we are intelligent life and stop. Then they are like, "Oh shit sorry dude. We didn't know. Here, share all our cool technology, join our Galactic Federation, and let us hang out on your planet in harmony and we'll teach you all the mysteries of the universe and we'll turn your planet into a peaceful prosperous Utopia".
Now you might feel a bit raw about them killing a billion people, especially if that included people you cared about, but you'd still be nuts to turn down that deal - and in a few generations nobody would care - just all an unfortunate, but understandable misunderstanding.
Well that's what already happened to all the non-white races when motherfuckers when Whites showed up in their high-tech ships and gave them technology, but they're still bitching about it.
Fuck them. The only thing stopping us living in peace and harmony in a Star Trek future is these tribal fucks who just wont let it go.
And if they actually built Wakandan Kang nigger tech and came to our shores first, I doubt they would have been as kind.
