Not wild at all. You can obviously roleplay however you want.
But you can't call it a faithful portrayal without being able to measure it against something to be faithful to. I'm not arguing about the play, I'm arguing about the terminology.
You can make up any terminology, and "standards" that you want. Doesn't mean that anyone else will agree with you when you use common descriptive language that is frequently used in RPGs. You can say you define "up" as "down" according to your terminology, just expect pushback and people telling you that it doesn't work that way.
