Maybe go lookup the entymology of "slavic" and then consider how stupid your hot take makes you look.

It's not about their etymology, it's about the origin of the word "slave" in English language that stems from Slav:

And so if you think carefully about the fact it's a term used to refer to a group of people who might be the only ones who's opinion on whether they're okay with it matters, but also how it's not a commonly used programming term...

I mean it must be pretty awful for Slavic people to realize that "slave" comes from their name in English/Latin and they are by default viewed in a biased way. Similarly how Slovenes and the word "slovenly" go along.

They have legacy status
