Students criticize protest on Facebook

The incident has ignited debate over whether schools should be able to punish students for online postings.

Angry reaction to the protest showed up almost immediately on a Facebook group set upfor students of Birchmount Park Collegiate, with thoughts posted by classmates and students from other schools.

"Too bad a bunch of you had to act like idiots today at your protest. If you want support, that's not the way you go about it," one posting said.

One user wrote that while the protest was not a "good representation of how we felt" and made some look like "stupid ignorant teenagers," it was still "a job well done" because it was liberating.
