Please go read this by Bully and John on how to help get rid of sexual harassment at Comic-Con.
While I've never been to Comic-Con, having had John and Bully as friends for many years, I trust what they say (besides, they are the kind of folks you can trust). The comic and graphic novel scene is very neat, and it's a shame to let a few guys who can't behave ruin it for everyone else.
And Hurray! to John and Bully for doing something about it. Join the effort. Click on the link in the first paragraph.
