How about something in Esperanto?
It was created by L. L. Zamenhof, a jewish ophthalmologist from Białystok, then part of the Russian Empire, but now part of Poland (as per Wikipedia) => european language.
Esperanto’s vocabulary, syntax and semantics derive predominantly from languages of the Indo-European group. A substantial majority of its vocabulary (approximately 80%) derives from Romance languages, but it also contains elements derived from Germanic, Greek, and Slavic languages (as per Wikipedia) => at least not a 100% romance or germanic or slavic or … language.
It would at least take away some portion of favouritism because it’s not a language from any european country (like English or French), it would be equally not understandable for all of us because it’s not being officially taught in schools (is it?) and again no favouritism like it would be the case for Latin (not everyone had it in school).
Or we could dare find a motto (or translate OP’s motto) in PIE, but I’m not a linguist, only a lingthusiast.
Why would it suppress left politicians? It’s not like any of them have multiple extremism convictions, that’s usually rightwing politicians.
I hope some afab folk will chime in, it’s ridiculous that only amab people have comfy jeans and things actually resembling pockets.
MOGAI is imho the best because it is truly inclusive of anything that isn’t cis- and/or heteronormative (including heterosexual and heteroromantic e.g.) and intersex people who would otherwise be invisible. As you said, it would be a term that wouldn’t need to be constantly extended whenever we figure out that there is more to the human experience.
“MOGAI-Community” also rolls off the tongue nicely.
In my day to day, I call myself queer (that includes for me anything from LGBTQIA+).
Ok, I see now how that could happen - I forget people would abuse a law like that.
Thanks.
