I don't understand where the problem arises exactly, there is no racist intent in its usage here, it's just a word, it's an empty container and we fill it with meaning. In this context it just means "customization", sure it's not a completely made up term and its origin is lowkey racist, but, as you stated yourself, not many know at all of that connotation, they go on to use it despite never meaning to use bad language on purpose, because it has simply acquired a different meaning, it was just the lingo they happened to find in the community.
There's plenty of words that had historically been bad and then became good, same the other way around. I believe that's the case here as well.

Even so, if an alternative word is proposed and favored, even just plain "customization" (which I feel would be better than replacing it with a lingo word, as it would make it easier for newcomers to understand what is being talked about more easily), I wouldn't be opposed, the main thing is to be able to convey the meaning, that's what that matters most in the end

A lot of you need your blood pressure checked

It's not a pejorative toward asian men at all. Not everyone is as racist as you.

I think the racists connotation came first, but I also heard it explained as an acronym - "Race Inspired Cosmetic Enhancement"

For the sake of the American asian diaspora minorities again?

This reminds me of attacking those girls for wearing a kimono or cheongsam to a prom. The Japanese and Chinese living in Japan and China certainly don't have an issue. It's the Japanese/Chinese American minority community who has built their identity around it, and feels threatened by the use of their traditional clothing. Fine, the prom is in America, it's an American problem in an American space, the local diaspora have a say there.

Unixporn on lemmy.ml isn't American(or any one country) though, clearly there are a variety of people from every corner of the globe here. This place is positively cosmopolitan. I don't see a reason why the "rice" term still has to be protected despite being a global platform. Just like it's fine for any tourist to rent a kimono in Japan, it should be fine to use rice as a term here. Unless this platform were to officially become Amerian(or any other country like Fedd.it etc), this problem shouldn't exist. I'm an rice eating asian myself, I'll be glad if people were to associate rice with customization.

The Asian American community should keep in mind that the internet isn't always an American space by default. I don't think they should be gatekeeping everything Asian on a global platform.
