In sociology class, a decade ago, I did presentation on 'Japanese sexuality'... showed videos of high school girls and explained Japanese fixation with lolita complex and related perversions. Got at least 3 written complaints and 5 verbal complaints from other students to the prof (that I heard about or received copies of), out of a class of just 25. I also got an A+, prof thought it was well-researched and I had obviously shown an interest in my research topic... haahaa of course I had...
purely academic of course
