The leftist no-fun police at it again.

Via Telegraph:

University of Colorado Boulder tells students to avoid costumes including cowboys, indians, white trash or anything potentially deemed offensive.

University students in America have been told not to wear “offensive” halloween costumes including cowboys, indians and anything involving a sombrero.

Students at the University of Colorado Boulder have also been told to avoid “white trash” costumes and anything that portrays a particular culture as “over-sexualised” – which the university says includes dressing up as a geisha or a “squaw” (indigenous woman).

They are also asked not to host parties with offensive themes including those with “ghetto” or “hillbilly” themes or those associated with “crime or sex work.”

In a letter, officials said: “please keep in mind that certain Halloween costumes inappropriately perpetuate racial, cultural, and gender stereotypes.”

The move comes at a time when pressure is mounting on one of the most famous American football teams to change their name because of the offence it causes Native Americans.
