A day off? For some racist comments? Nation of pussies indeed.
You have a day off for a school shooting involving deaths. Hell, my school had a junior off himself with a rifle in a campus parking spot one night at the beginning of the semester and we didn't even get anything beyond 'counseling services are available'.
For something like this? Pay the Janitors/maintenance guys some overtime to clean it up/paint it over, and have the Dean or such write a strongly worded letter.
