"We are appalled at what took place and in no way condone this type of activity in our schools," Hempfield School District said in a statement. "Neither the dress of the invited guests nor the performance was appropriate in our school setting."
I read the lancaster article, in which they explain that the students were indeed wearing inappropriate clothing, showing skin in places that people in high school shouldn't show.
Though this article focuses on the drag and LGBT part, implying that the school is appalled by the drag show as a whole, and the LBGT students as a whole.
