The Wikipedia definition seems to indicate it has origins as a racist term and I’ve never understood why unix users have adopted this terms instead of something benign like “themes” or “theming” which I remember being in use long before I ever heard “rice”. So what gives? Why use “rice” instead of “theme”?
Following that logic we should rename lots of things, as any word can be use in a despicable way. I get your point. But again. It’s just the name of an app.
The word has been considered a serious slur for years. If, by chance, you wind up naming your project with a tier-1 slur, yes, you should absolutely rename it.
Any word CAN be, but in this case you have a group of people telling you it IS hurtful to them. Those aren’t the same thing.
