Vacca praised a group of 70 students after they camped out overnight in the school library last week to protest the results of the presidential election and to announce their worries about the direction of the country. The students wanted to meet with Colorado's political leaders to get assurances that they were being heard.
The students said they worried about war, a return of the draft and the future of the environment after the election in which they could not participate.
"In an age where narcissistic college students riot in an inarticulate drunken stupor, you have students here at Boulder High School, principled, thoughtful and yet scared of four more years of pre-emptive war, the Patriot Act and an increase in militarism at school through the No Child Left Behind Act," Vacca had said.
But other people said they are upset students and teachers are allowed to put on such a performance, and some say the high school students are being manipulated by the adults.
"These kids are being used to promote an extreme leftist point of view on the taxpayers' dime," Boulder resident James Lemons told KMGH.
He said other students who saw the tryouts and were upset by the presentation discussed it with their parents but are afraid of speaking up because of the political environment within the school and in Boulder, considered the most liberal city in Colorado.
The principal said Lemons' accusations and allegations are untrue and unfounded.
"I feel that the school and these students have been accused without being able to confront their accusers," Cabrera said, adding that no student or parent had talked to him about the allegations. "Why would someone do that?"
