I wasn't referring at all to the video, I was referring to the formation of a pro-gay club at the school. Whether or not the video should be shown is more complex.
The school district agreed to present the video when it settled the case. The school district itself agreed to show the film. So the question is whether the settlement is in fact binding. Why would a legal settlement (agreed to by both parties) not be? This seems to me to be a matter of contract law or whatever, not free speech.
The question here is whether the school district has the right to go back on its word. A radical Muslim would agree with you, because us infidels are subhuman and can be lied to/cheated/etc. But I'm not seeing support for breaking contracts in Christian or Jewish traditions. What sort of a "conservative" are you? The idea that any party should be able to break a contract just for the heck of it is not conservative, it's radical.
I thought the question was whether children could be forced to view the film.
