Here's a link to the text of the Circuit court opinion: http://www.ca1.uscourts.gov/cgi-bin/getopn.pl?OPINION=07-1528.01A
Note these statements:
"Given that Massachusetts has recognized gay marriage under its state constitution, it is entirely rational for its schools to educate their students regarding that recognition."
and
"There is no allegation here of a formalized curriculum requiring students to read many books affirming gay marriage."
But there IS a formalized "tolerance" curriculum that starts in KINDERGARTEN and goes all the way through high school.
A Massachusetts *court* may have recognized it but the people most assuredly have not.That's why the forces of "tolerance" in this state fought so desperately to keep the issue off the ballot,lest numerous polls prove correct that such a measure would lose decisively.
