ST. CATHARINES, Ont. — One Ontario university has already laid down the law on what costumes will be “prohibited” at the campus Halloween party this year.

Brock University’s list includes ankle-length robes worn by Arab men, makeup depicting Japanese geishas, anything with the Confederate flag on it, and costumes that depict Caitlyn Jenner, the transgender celebrity.

According to the school’s “costume protocol” developed by the student union, traditional or religious headdresses such as feathered bonnets and turbans, are also off limits.

“If a member of your party is denied entry because of their costume, they will be escorted to a space where they can change or remove the offending item,” students have been told.

Brock’s list of political correctness is just the latest in a trend that’s picking up across North America. The University of Florida recently issued a memo reminding students they can submit a “bias incident report” and seek counselling if they encounter an offensive costume.

Last year, when Yale University sent out a mass e-mail about appropriate Halloween wear, Erika Christakis, a lecturer in early childhood education, wrote back wondering if administrators had lost faith in the ability of young people to “exercise self-censure, through social norming.”

“Is there no room anymore for a child or young person to be a little bit obnoxious ... a little bit inappropriate or provocative or, yes, offensive?” Christakis wrote.

Brock University’s student union developed its costume rules following outcry two years ago over a group of students who dressed in blackface as the Jamaican bobsled team.

In a Friday statement, Brock University said “applauds our student union’s efforts to educate people about the importance of being respectful in what we say and wear, including at Halloween.

“Brock is a vibrant, tolerant community where people of all cultures, religions and orientations are accepted and welcomed,” the statement continued.
