<snip stuff about the meaning of 'hentai'>

 However, I don't see Yaoi as perverse, especially those with a decent storyline.
 Hentai is something that is
downright twisted and out of the league.  This is just my two cents on it.
And just to make sure, this post it NOT meant to start a flame war of any kind.

We obviously have different version on "H".  To me, and to what I have 
been told, a show like "Cutey Honey" is 'H'.  "Urotsukidoji", though, goes 
beyond 'H' and straight into porno.

Umm... there's a difference between three 'words' that all come from the
same word.

"Hentai" is sick and twisted and perverted.
It also means 'changed'.

"H" means something not so perverted, but has stuff like shower scenes,
etc.

"Ecchi" is more gentle than 'H', and it can be considered as a compliment
at times.

Cutey Honey is 'H'  (half the show has a naked or half naked girl in it)

Urotsukidojii is 'hentai' (it's totally perverted)

Ranma 1/2 is sometimes 'ecchi' (it's occasionally got half naked girls)

Kun-chan...
