A very interesting essay--I can't speak to its accuracy because I haven't gamed much, but it sounded reasonable, and is the best thing I've seen about paying attention to your student's awareness while you're teaching.
I don't think it's quite right about why women hate having their player characters raped. The essay focuses on the implied real-world threat during in person gaming, but my bet is that getting a character raped in anonymized online play would still generally be unwelcome. There are women who like rape fantasies, but I suspect they would at least want a clearly marked context, and gaming in general is not that context.
