I've read all your comments on the various threads and a central theme seems to be the following question: how does sexism fit into all of this, isn't this just harassment/stalking? It's a fair question. Recall that sexism is discrimination based on sex OR behavior that fosters stereotypical/hurtful attitudes and roles. The attacker did both here. He attempted to drown out the technical ability of the victim by, during her technical presentation, spamming pictures that quite literally turned her into an object. This is a manifestation of classic behavior where men value women for their appearance only and everything else is ignored. Had that attacker had his/her way, this would have been the reality; all the attention would have been on her appearance and no attention would have been paid towards her technical presentation. His/her goal could not be more clear. To tie the goal back to sexism: what the attacker wanted is both a distinguishing treatment based on her sex (the first definition) AND a behavior that encourages ignoring the technical ability of women in favor of focusing on their appearance (the second definition).
I hope this makes my use of the word sexism clear. I welcome further communication here in this thread or at my personal email, which can be found in my profile.
Sorry if I only reply now, I was traveling. Also, I can't think of a useful comment. I just see it very differently, and the reason I ask "why has it to be categorized as sexist" is that I worry about the implications. For example if it is assumed that it is demeaning for a nude picture of a woman to be posted, but not if it was a nude picture of a man, the implication seems to be women should somehow be ashamed of the way they look nude.
I probably can't describe it very well, but I sense lots of weird implications of calling it "sexist" which I think are not really what the people calling the sexism flag had in mind.
