You're missing the point.
To start censor the word "vagina" in the first place, because there are minors in the audience?
WTF? 
Prudeness gone wild.
I salute these kids for revolting against the system, taking a stand against censorship.
They're essentially fighting for the freedom of speech, freedom of expression, just like the fathers of the constitution did.

Nah, I don't think I'm missing the point. I can see where the school would have reservations about open mic performance material...and I don't think I'd drag my kid to see the Ginie Monologues... however brilliant it is. The school said that had the girls wanted to put on a performance of the play in its entirety and advertised it as such... they would have agreed. In fact, there are lots of high schools that put on the performance for Valentine's Day every year all across the continent. So it wasn't a question of censorship, per se. Just the forum.
Perhaps you're just arguing that the States is more puritanical regarding sexual matters than other parts of the world. In that, you are correct, and you are correct in attributing this to the influence of the religious right.
Anyway, no harm, no foul. The girls got a one-day detention, and in exchange they got to talk to the author of Ginie Monologues and world-wide publicity. I hope at least one of them fast-tracks a career in the arts out of this!
