In fact, you're saying its 'obnoxious' to say that penis inversion is 'plastic surgery'.
That's even more interesting. It seems to me as though you're treating the surgical flaying and inversion of a penis as some kind of holy, sacred rite, that achieves the mystical and impossible feat of changing sex. Not merely a surgical procedure.
It's blasphemy to say it's a medical procedure, is that what you mean? I hope you answer, I'm really keen to understand the reasoning.
