Mark Evanier posted a link to this essay and after reading it thought it would be worthwhile reading.
I remember from my early con going experiences that female attendees were generally girlfriends or wives who were being dragged around, or those few female professionals who worked in the industry. Often you wouldn't see more then a couple ladies, until it was time for the 'costume' contest when they would magically appear. The past couple of decades has seen an amazing increase in the number of women both reading and creating comics. I think this is a plus for all fans of comics and for the industry itself.
Sadly, I have also overheard, witnessed and been told stories which mirror those in the essay. I am in total agreement that this type of behavior (no matter where it occurs) should not be tolerated. I'm frankly surprised that the SDCC doesn't have an established policy on this sort of thing and think that the organizers might want to consider creating one.
Anyway, see what you think:
