Third post here, but this thread cracks me up, and I find it fascinating just how wrong those people are. I've already discussed the castles themselves, but hadn't really looked into the community note. Here's a translation:

This is racism. [links to racism "definition," I'll get to that in a bit]

Furthermore, the example used is of a house belonging to an indigenous people, not representing real castles.

DEBONKED! Way to miss the whole point, community note. "To make your entire point, you called this thing that obviously isn't a castle, a castle, you liar!" Uh, that was the point.

Video demonstrating what the homes of African tribes are like:

Yeah, relevance? Everyone already knew it was a house/hut. The stupidity levels are off the charts here.

Thread showing African castles: [links to thread I've already discussed that lists a bunch of foreign-built castles built in Africa.]

Excellent source, community notes; a random Twitter retard being flat out wrong. Try harder. Do better.

Now, as to the "racism" link...oh, boy, what a doozy. Also translated:

Racism is an evil that, unfortunately, still affects our social relations.

...it's a form of prejudice and discrimination based on a controversial term, which is sociologically revised and from which genetics also begins a review: race.

The translation is a bit rough, but this seems to be the classic "race isn't even real, chud" argument. "Racism is stupid and ignorant because race isn't a thing!" *sigh*

In the XIX century, it was understood that the skin color and the geographical origin of individuals promoted a differentiation of races.

Correctly, yes. Call it "race" or something else, people from different places are obviously different.

By blending culture and physical aspects, the early anthropologists established a hierarchy of races, which sometimes reinforced the domination of European white peoples over populations of other non-European ethnicities.

Such circular logic. No, "hierarchy" (more like preference) was a mix of accomplishments, in-group preference (the good old days when whites were allowed such a thing), and the like. Not even saying racism itself is good or anything, but the idea that it was just some stupid bigots being bigoted is a huge dodge. White people didn't "invent" race so they could put their own race at the top and use it as an excuse to rule over others. For better or worse, it was kind of the opposite. They did some ruling over others, which often convinced them they were better. If race was every used as a justification of superiority (and it was), it was usually after the fact. No surprise, but they have everything backward.

In these people's view, it really is as simple as some monocle-wearing rich Hwite Man look at his hand and going, "oh, look, I have white skin, and that guy has black skin. Due to the fake shit I made up because I'm evil, I can clearly determine I'm a better human. It's OPPRESSION TIME!"

racism it is an evil that affects the lives of many people and, as a relationship of outdated and wrong understanding, must be overcome.

Good luck with that. You'll never get there all the way, but we might have gotten close, if everyone hadn't decided to disparage and try to eliminate all white people, while lying about each race's contributions and accomplishments, and generally promoting racial supremacism for any nonwhites.
