Well, I know ASU hosts (or hosted) a yearly event where they post an anti-abortion group outside the Memorial Union that have billboards with grotesque images, my favorite is the rhesus monkey with the top of his skull removed exposing its brain, and they are out there to harass ASU students and tell them that abortion is bad.
Haven't been there in ages, so might not be a fixture anymore. Was the 4 years I attended the campus, and I was told they were there every year for MANY prior years.
Any time outraged students tried to engage with the people with the misinformation and bullhorns, Tempe police were there with handcuffs. Can't be within shouting distance of the evil mother fuckers for more than 90 seconds without the STUDENT being threatened with disorderly conduct.
So ya... seems like an apt place to have this kind of clash.
