I am curious about your stance here. If students at a school (public or private) were using myspace as a tool to embarrass the school or a teacher or fellow student, would you think it was the school's obligation to do something about it?
Yeah. If someone else is brought into it and defamation of charcter is going on, then the school or other party has an interest in doing something about it. I'd think dealing with it on an individual basis in that case would be a better option than simply banning it for everyone just because some might abuse it.
It sounds like the school decided on this policy recently. If it's a change in policy from what the parents and students originally signed up for, then I think they're out of line. If it's clearly stated in the rules from the beginning and the families agree to it at the start, that's different.
Moral issues are different. God has established right and wrong and expects His people to behave in an appropriate manner but in areas where Scripture isn't clear about things (although I know myspace can be abused) I'm not comforrtable with people imposing standards that there isn't much justification for.
As far as the argument of *sending kids elsewhere*, that isn't always an option. We live out in the coutry and there's not much *elsewhere* to go. Options here are really limited. If you don't like the local Catholic scool or Christian school (note singular) that doesn't leave much.
