School allowed to bar from extracurriculars for ...

Should a school be allowed to bar a student from extracurricular activities for Internet speech?

A federal court (it's unclear to me which one) has again denied a student damages. A girl running for student body president at a Connecticut's Lewis S. Mills High School called members of the school's administration the "douchebags in central office" on her LiveJournal, an online journal website. The school found out and barred her from running for Student Body President.

I could see this if she wrote it while in school. But, that's not even a factor. It's basically saying that if it COULD be read by members of the school's community and is vulgar, that they can discipline based on that speech. This is not to say that they could discipline her academically via suspension or expulsion, the decision was quick to point out that the school has much more leeway in doling out discipline when it comes to extracurricular activities.

I just think that speech on the Internet, even if she DID write it on school grounds, is speech made to the void...and, therefore, not under the authority of the school.
