Well, it'd be a much longer post if I'd include every instance of slavery that ever existed. But you're ignoring the argument. You do realize they didn't invent how slavery works when they brought it to USA, right? Yet you say nothing compares.

And yes, the logic is exactly the same. You can only say that it's ok for an ethnic group to use a slur that was used against them to dehumanize them during a time of mortal oppression, if it's also ok to do so by the other ethnic groups that experienced the exact same justification from during other times in history.

Also, you're not seriously claiming the history of specifically slavery in the US, was worse than the Holocaust, are you? Do you even know the details of what they did during ww2?

As explained, it has happened to everyone. Everywhere. You need to learn about world history a bit more.
As I already made clear, there have been times, not just the time with the USA, but also other times, where a specific group of people based on the color of their skin or place of origin have been targeted to turn into slaves. For example Slavs, a.k.a. Slavic people, from which the very word itself originates. Slavic people are white, didn't seem like you got that implication.
Slavs were literally turned into slaves because of their place of origin, the same way Africans have been turned into slaves throughout world history from time to time.
But originally, and times in between such cases, it has been about people being turned into slaves due to debt or as captured war prisoners and civilians of the lost villages/towns/countries.

Africans have turned other Africans into slaves as well, because as mentioned, the norm throughout world history has been due to debt or as results of conflicts. Africans have also been turned into slaves by Asian countries too, on occasion. By different empires too, and so on. A lot of slaves have existed from everywhere in the world, throughout world history.
USA is a very young country. Slavery has existed for much, much longer.

By its very definition, it's about the lowest societal class in the social hierarchy throughout mankind's history, being below all other.

Ergo, it's classism. Pure and simple. It has just been intertwined by racist motivations occasionally throughout world history, but not always. Even now, it's only due to debt in modern times. Well, debt and a certain religion.

I love how you glossed over the part about how if going by your very own logic, it should be ok for Jewish people to be the only ones using those slurs listed in the previous reply.
See what I mean by how certain words should just never be used again in any person-to-person manner anymore? You can't say the N-word is ok to use only by one ethnic group, without saying Jewish people are the only ones allowed to use those other slurs.
Just make them all not allowed to be used in any person-to-person manner, and let history bury the negativity once and for all. I'll bet you didn't know about those German slurs for Jewish people, did you? That's because they allowed them to be buried in history.

To be clear, I'm not Jewish. I'm Scandinavian and agnostic, and couldn't care less about your culture wars. But you're actively causing harm to yourself and others, by not letting yourselves normalize the dynamics between everyone. You'll always be at odds if you're always emphasizing the differences, and it will always have a negative connotation because of its etymology if you keep using that word even if you yourself feel that it empowers you.

I'm going to assume you enjoy kdramas since you're here commenting on an article about a kpop star, so maybe this will affect the way you think and make you wonder if it's ok to let the past be in the past or not:
The country with the longest systemic slavery, was Korea. So if you dislike the USA for having had it for a comparatively very short amount of time, what do you think about Korea?

Except I CAN use that as an example (what is up with your constant caps for emphasis?), because it's not about hierarchy. To a Jewish person, they feared that more than any actual African American slave ever feared the N-word. Not just the genocide and gas used on them, but also the actual human experimentation, made that the scariest phrase to them.
But fine, if you want a literal comparison, then the Holocaust Encyclopedia have a lot of examples of slurs they used to remove Jewish people of their humanity, literally the exact same description you just gave for the N-word:
Parasites
Pests / Vermin
Rats
Bacilli / Bacteria
Sub-humans
Jewish pack / rabble
Financial Jews
Alljuda (there was no translation given for this word, but I'm pretty sure it just means "All Jews" but the encyclopedia explains it was used in propaganda as a reference to a conspiracy theory)

^ All of those words were of course said in German, but the encylopedia provided the translations and explanations.

They were a bit more creative in some ways, and way more literal in other ways (I guess that's the German language in a nutshell sometimes), but you're saying it's ok for Jewish people to use all these slurs as colloquialism the exact same way you describe the N-word being used by African Americans?

As for slavery, the African Americans are not unique. Everywhere there have been slavery, of all different kinds of people in the world. If anything, slavery in itself is pure classism; not racism. It can target specific groups of people by the color of their skin, on a case-by-case basis throughout history such as the case with USA, but that's more the slavery and racism being combined for those specific cases; but slavery itself isn't equal to racism.

But like I said, the word slave is derived from the Slavic people, from back when they were slaves.

Here's a fun little fact for you: Do you know WHY it's called "slave"? It's not because people of African descent used to be some of them. It's because it started with Slavic people in Europe. As for slavery in modern day, it's STILL a thing. It's just not in the US (although the exploitation of undocumented immigrants is close to it, except they get freedom outside of work which real slaves never get).
As for the N-word, it's because it's still used that it still causes problems to flare up. It doesn't matter who uses it. It's like saying Heil "Mustasche" is ok for Jewish people to say.

Certain things just needs to be erased. Period. And the UN needs to stop messing around as it turns a blind eye to the underworld of human smuggling, and in some parts of the world actual slavery.
UN have published reports on the ties between human smuggling and criminal organizations and that the system enables it instead of stopping it, as well as on slavery around the world.

The UN has yet to do anything about it. Because no politician wants to talk about it openly.
