What is a constructive way to register that one is offended by a campus event?
I ask this because my house just threw a Cinco de Mayo party and a member of campus decided that this was racist of us. He took special offense to our unicorn pinata, which was hung out the window for display for most of the day before the party, because unicorns are apparently especially racist. (The whole sequence surrounding the unicorn, which included pictures on the internet and angry ranting, made me flash back to the old ehell tale of the Racist Bagels.)
I'm not challenging his right to be offended by the party, but he expressed this offense by calling us names and swear words on our Facebook event, defacing our advertisement posters, and yelling, and then on being told that this wasn't appropriate behavior, doing a lot of implying that being rude is necessary to get people to pay attention. I think we can all agree that none of the above are appropriate behavior. So, as an intellectual exercise, what would have been a way for him to express his sentiments about the party and try to get people to pay attention without being rude?
