Seriously?
It's a sexual education seminar for the undergraduate student body, put on by the school's sex ed department and their Women's Center.
The description on the full flyer literally reads (bolding the parts they did):
The name's just an attention-grabber; my undergraduate school called theirs "Sex Week" (it was a series of seminars), but it didn't mean the purpose was for use to go around screwing for a week.
It (the name) is unfortunately the way these kind of things have to be marketed to college and high school aged students to get them to attend, because no one in that age group is going to something just called "Sexual Education Seminar," as much as they (especially the newer freshmen) are really the ones that need this type of information.
I agree the timing ends up poor due to the case, but considering they look to be bringing someone in for this, it was likely scheduled well before it.
But I'm unsure that not having any sex ed seminar - especially since this is dealing with consent, safety, making the right decisions, and so on - is much better or the right thing, either.
