The problem you are mentioning is that school administrators will want to ban Wikipedia on the grounds that students may look up material they find objectionable. The problem is, the responsibility still lies on the user to refrain from viewing it! As an optional system, users could easily opt out of filtering, making this is a very ineffective solution. Whereas, a fork would be very useful. Since we are working with open content, anything on the Wikipedia can be used on the Edupedia. The Edupedia could also have a different way of handling user submissions (perhaps requiring a peer to OK an edit). Administrators can ban the Wikipedia.org site knowing that Edupedia tries their hardest to remain appropriate for educational institutions. And article forks can happen and will be useful. (You had mentioned you felt a fork of [[homosexuality]] would be more appropriate for school.)
A fork will make a site that is "appropriate" for schools. A filtering system will introduce several problems. Someone posted that Jimbo would support a project like this.
The high school I attended would probably have blocked Wikipedia on the grounds that it was a "Chat/Message Board" site. Whether or not a logged in user can see a photo of a clitoris would not help.
