I’m sorry but how is that unique to the US, that’s literally all of human history and all humans in human history have always had an “other’”.

What makes the US of any more note, if anything, is just the level and formalization of such disgraceful treatment of the “other” that, started with the colonialization of America and the slave trade that boosted it.

Do I think it could be said that this is not the first time that such a thing has happened in history? It’s just this cycle, who knows how long these Cycles go, and hopefully it’s when we eventually evolve to get off of.
