I suppose.

But I think of of Rydras points is that being a soap opera caricature (or underwritten, or a Marty Stu, or even having no lines/screentime) doesn't really seem to stop a lot of fanfic writers who happily supply whatever text, subtext, backstory, or depth they require for their favored male characters.

So, if fanfic writers can spin gold out of little or nothing for so many male characters, why are the deficiencies of female characters seemingly in so many cases such unsurmountable showstoppers?
