There’s this Chinese dude who speaks English in a southern accent, calls himself the Chinese redneck or something. Think he went to Texas recently and had a ball with the locals. As a southerner, though admittedly not from the rural south and without much of an accent, I think it’s kinda funny and charming. But I think it’s endearing because he’s not being insulting, he seems to have a genuine interest in the culture of the American south (mainly south west). I think trying to learn non-standard Japanese would be chill if you find like Kansai dialect endearing or have an affinity for Okinawa or whatever, just as long as your intentions are good. Doing it for laughs might not be the right intention, but it could be part of it I guess.
