In case you haven’t heard, the Montgomery County (Maryland) Public Schools tried to implement a sex education curriculum that endorses homosexuality as a normal and amoral (not “immoral,” “amoral”) lifestyle choice. Whether or not one agrees with that proposal, the fact is that the school system gets its facts wrong and makes theological arguments – including making statements about the proper interpretation of the Bible and other religious texts and endorsing specific religious groups over others – in the proposed course materials. Eugene Volokh does a good job explaining the problems.
You can view the court ruling against the school system here.
UPDATE: I should note that the question of whether or not the school system can implement this curriculum is still open; the ruling above is only on granting a restraining order.
