A year or so ago students as a residential college at UC Santa Cruz held a science fiction themed event that celebrated things like spaceships and aliens, SciFi books, movies and TV shows, things like that. It's part of the monthly College Nights events, and are mostly just dinners in an informal collegiate setting. Entertainment ranges from a variety of music or comedians, dancers, or just watching a feature film. Former parties held on College Night included “Midnight in Paris,” at which French food was served, and “Harry Potter,” which featured turkey, potatoes and stew. For this particular dinner, they chose Mexican food, mainly burritos and tacos, for no other reason than they "hadn’t yet had Mexican food for one of these events and couldn’t find any food that was space-related," according to Scott Hernandez-Jazón, one of the student organizers.
The next day, after an onslaught of complaints, UC Santa Cruz administrator Dr. Carolyn Golz swiftly issued a public apology for allowing the students to serve burritos in the presence of spaceship drawings: "This incident demonstrated a cultural insensitivity on the part of the program planners. I recognize that this incident caused harm within our community and negatively impacted students. We would never want to make a connection between individuals of Latino heritage or undocumented students and ‘aliens,’ and I am so sorry that our College Night appeared to do exactly that. As a result of this incident, I will require cultural competence training for Programs staff, in addition to implementing mechanisms for future program planning that will ensure college programs are culturally sensitive and inclusive."
Another example of how easily it is for people to get offended, I relay to you this a semi-personal anecdote. As you may or may not know, school lunch menus are generally made up a year in advance, and usually just get recycled from year to year. Whatever you had on the first Tuesday in October last year is likely what you'll have on the same Tuesday in October this year, or thereabouts. It's just a matter of how the calendar falls from year to year. My high school Alma Mater, Princeton High School in Cincinnati, has been doing that since at least the time I was in school there. A few years ago, it just so happened that the featured lunch on a particular Wednesday in January was fried chicken, mashed potatoes and gray, corn, cornbread, and for desert, watermelon was served. I can't see how anybody could be offended as such an awesome meal at school. Oh, but they were. It also just so happened that that particular lunch menu fell on Wednesday, January, 15th, which also just so happens to be the birth date of Dr. Martin Luther King, Jr.
Food was thrown, tables were overturned, a riot broke out, and students walked out of school. Sheesh.
