Hasn't this happened to all of us?

It's 3 a.m., and you've just been triggered by the thought of someone's Halloween costume. What do you do?

Well, if you're a student at the University of Florida, there's no need to wait for business hours. You can get the counseling you need right now, 24 hours a day, seven days a week.

In a memo to students posted Monday, UF discussed the "harm" that arises from certain Halloween costumes. It wasn't until a few years ago that offense at Halloween costumes became mainstream, but now that it is, colleges and universities are issuing warnings before the holiday.

"If you choose to participate in Halloween activities, we encourage you to think about your choices of costumes and themes," the school wrote. "Some Halloween costumes reinforce stereotypes of particular races, genders, cultures, or religions. Regardless of intent, these costumes can perpetuate negative stereotypes, causing harm and offense to groups of people."

The school added that if a student is "troubled by an incident that does occur," they have resources available to them, including 24/7 counseling. Also, students can tattle on their classmates to the school's Bias Education and Response Team, which seeks "to educate those that were involved, and to provide support by connecting those that were impacted to the appropriate services and resources."

What tends to offend? Well, for one thing "cultural appropriations" like wearing sombreros.

But of course, nearly everything is appropriated from another culture. And that includes the politically correct values that Western, white-liberal-dominated university culture is producing on a grand scale nowadays. Lest you offend your peers, there's really only one safe costume to wear this Halloween: the Greendale Human Being.
