Watching a film in class about dolphin slaughter in Japan

• Professor: So I know this may be difficult for a lot of you to watch, it's very graphic and it's so terrible what's being done to these dolphins. Does anyone have any questions or comments?
• Class: *sad faces* *crickets*
• Me: *raises hand* nearly 100,000 cows are slaughtered every day in the US for food in a similarly inhumane fashion. If this seems wrong to you all, you should look at your habits and re-assess your values on a personal level.
• Class: *angry faces* *crickets*
