More on trigger warnings in the classroom, from Jade E. Davis at Talking Points Memo:

I am not what students expect. I am a medium-tone, shortish black female with natural hair that isn’t quite kinky enough to go into an afro. I am hippy. I come across as sweet, and I push my students in ways that make them uncomfortable. Because I am me, students assume that my teaching about media and popular culture, or media and society at large, will take a very specific trajectory. To an extent, it has to. For many students, realizing that, as the professor, I am the person my students who has knowledge and power over them, is traumatic. For other students, though, it is liberating. This is what the recent article in the New York Times misses.
