If you’re complaining about “convert-itis”, found in religious conversions, heritage discoveries etc, I can see the point. “Now that I am [x], I’m going to do it better than you all did and teach you using my majority culture understanding”.
I think it’s “mostly harmless” but probably annoying to the community they try to “improve upon”.
I did it once. In my mid 20s, going through religious quest phase, ended up Eastern Orthodox (christian) and I was gonna “do it right”. The local community tolerated me. Lasted about 6 yrs in it. It was fun, learned a lot, but I know I was insufferable to friends and family.
One church I visited was throwing out bulletins with icons on them. I gave a speech to the Russian priest about how sacred they are, and mostly repeating some shit I read on a 90s era website run by convert fanatics. He just sighed, waited ’til I was done, and corrected me with a few words. Don’t remember what he said tbh, but it must’ve worked.
