I've noticed some weird attitudes about female comics fandom recently. I... think anyone who says that "comics aren't for girls" (like this) should read this, from The Comics Journal. Read the whole thing, even after the main essay ends & it goes into info on the magazine issue. Like this bit:
A word about our cover artist: Moto Hagio is one of the most important creators to rise from the world of Japanese manga. As a guiding member of the Magnificent Forty-Niners, she was one of a select group of female manga-ka who entered what was then a backwater, male-dominated section of the Japanese comics industry and shook it up from top to bottom, revitalizing it in the process. As you'll read in the following pages, modern shoujo manga was essentially plotted and shaped in the cheap apartment Hagio shared with Keiko Takemiya back in the early 1970s. In a very real sense, an industry was born in these women's wake.
Yeah, read that paragraph again. So, do you think that that sort of thing can't happen here? or shouldn't somehow? Are we more sexist than Japan in the 1970's, really?
Anyway, the main point I draw from that essay is that manga is much much huger commercially than American "mainstream comics" (which long ago ceased to be with either mainstream or comic) because it's much much broader artistically.
Wow, actual thematic & genre variety as a means to draw more sales? What a shock!
