Ricing is a racist term. I am telling you right now that it is a racist term referring to a type of car modding that Asians are stereotyped as doing. It is explicitly used to deride and exclude Asians from the car enthusiast community. Anyone who’s into cars or around people who are has heard this term, but you can Google it if you want.
What does it say about you that you’ll deny basic, well known facts to defend using such an exclusionary term in a tiny community with a large amount of Asians in it?
If you want to do the research be my guest, but I’m telling you right now, I’ve only ever heard the term used to mock an Asian person’s car mods.
There’s you answer. It is disrespect based on ethnicity.
Then you should be fine with not using the term, right? Why are you working so hard to defend a word you claim you don’t see much? You have put all this effort into justifying using a word you have been told several times is racist that apparently other people don’t use according to you.
