I don't think a lot of people have read/watched this here. At one time the anime was a popular runner up to Cowboy Bebop/Evangelion/Trigun etc, although the manga is a lot funnier actually. If you haven't read it yet it's online (not familiar with the colorization). For me it's one of the funniest mangas I've read, more relatable to normal people than stuff that depends on meta humor.

Point A, everyone including Ranma knows he's a dude. Nobody ever gets confused except for strangers and psycho gag characters. Once people know about the transformation, they instantly accept his actual identity. It's called a curse, he hates it, and half the plotlines are about trying to get rid of it.

American fans sometimes described the series as a "transgender sex comedy," but in hindsight that was wishful thinking by weird people that would later become groomers (if they weren't already). There is no existential pondering over male and female experiences, nor is there any sex, or even the hint of sex.

Point B, the clear majority of trooners are girls trying to become men, not the other way around.
