Of course, the federal appeals court that rules California, the Ninth Circuit, held in 2005 that parents likewise have no constitutional right "to prevent a public school from providing its students with whatever information it wishes to provide, sexual or otherwise, when and as the school determines that it is appropriate to do so."
Strikes me that one's prerogatives as a parent are pretty limited. The only one we Californians can count on? The "right" to continue to pay taxes to support a school system that's more interested in indoctrinating children than educating them. Behold the judicial manifestation of the dearly-cherished lefty doctrine that the "village" (i.e., the state) can do a better job raising children than their parents can.
