If that makes sense

Completely.

And, wrod, to your last paragraph.

It comes from Star Wars TPM fandom

Does it really? I had no idea. I assumed it was imported from anime/manga.

The term really wasn't around before TPM hit?

I thought chan was an anime term that become popular in Harry Potter fandom when anime fans became interested in HP.

I've also seen the anime influence in HP fanart.

Anne's our anime expert, but a quick hunt didn't turn up chan used in that sense in the fandom, and most refs I've seen to the term are TPM.

Well, FWIW, most manga fans I know would probably object to the change in the word's meaning, since most meta-manga vocabulary I've learned is faithfully Japanese or direct translation. It should take a not-really-Japanese, just-clanging-off-quasi-Japanese-copycatters fandom to take a Japanese word and give it a new interpretation.

I've never seen 'chan' used in any of the anime fandoms. Or, to put it simply:

What Nutty said.

If someone has breasts and hips and is menstruating? (Or male of equivalent sexual maturity?) Not a child any more.

It isn't at all unusual for 12-year-olds to menstruate. IMHO they're too young to have sex, and any adult who has sex with them should be prosecuted.

We do have to accept that someone we legally title a "child" may not consider themselves a child.

Yeah, I'll happily accept this - thus the thing I said earlier about not referring to sexually mature teenagers of the Britney Spears variety. If someone has breasts and hips and is menstruating? (Or male of equivalent sexual maturity?) Not a child any more. There may be a whole heap of moral issues still in place wrt older people in positions of power having sexual relations with them, because of the relative power yada yada yada - but still, they're not children, imho.

This is an interesting issue in comics fic, specifically Batman and his Robins. The Robins have all been under the age of majority (yes, Dick [Robin I, for the non-Batfans] made it to 18, but he became Robin at the age of -- was it 13? 12?), so most Batman/Robin fic crosses that adult/child line.

But the Robins are most definitely not "children," in the common sense of the word. It's a lot like pre-18 Buffy, really. Who they are and what they do (the Robins) put them right out of the category of "children," just like pre-18 Buffy.

I admit I just blithely ignore the age issues, instead of thinking "How old *is* Bruce, anyway, and should he really be doing that with a 16-year-old boy?"

It isn't at all unusual for 12-year-olds to menstruate.

Nutrition being what it is these days, 10 is not altogether unusual any more. Secondary sex characteristics do not indicate the ability to make adult decisions, which is why the age of consent is closer to the age of voting than to the average age of menarche.

One could say that the presence of secondary sex characteristics takes attraction to the person in question out of the realm of obvious pedophilia. Which is not a condemnation, but taken as a general rule, not a ringing endorsement either.

There's a different technical term, 'hebephilia', for people who prefer adolescents. The ancient Greeks were technically hebephiles, not pedophiles.
