I understand that slang and curse words may not be as jarring or impactful to non-native speakers. I hear Finnish curse words regularly and they don’t bother so much.

My concern is that non-native speakers still use dictionaries and search engines, so easily learn about the meanings of words.

Additionally, I’ve tried to promote the GIMP in educational environments but the fact remains that teachers and parents are often averse to using the name.

Well, if for any reason you went "hey, what the hell does that mean" and decided to look it up:

    - (informal offensive) an unpleasant or stupid person: 
    - (informal offensive) a person with a physical disability, especially one that affects someone's legs
    - (informal) a limp (= a way of walking slowly and with difficulty because of having an injured or painful leg or foot )
    - a person who gets sexual pleasure from being hurt or treated badly

And it's not like this is super obscure or anything. The "most influential film of the 90s", Pulp Fiction, literally had a character that was "the gimp". This is pretty mainstream.

This is along the lines of "Hey co-worker, I found the best text editor the other day. It's called pizdă, you should give it a try! Pizdă seems like it would help you!"

But hey, GIMP is taking it back (https://www.gimp.org/docs/userfaq.html#i-dont-like-the-name-...) any day now. It's only been 25+ years. Any day now.
