Are you serious? First graders surprising their teacher on her wedding is nothing less than sweet. It's no different than if the trip was planned to see a straight teacher get married (something not all that uncommon). Kids were not forced to go, and I think the fact that all but two families gave permission for the field trip shows that it's obviously not an issue in their neighborhood. And who knows, maybe those parents opted out because they felt it was inappropriate for their kids to miss school for ANY wedding....
The fact that California schools and the California state superintendent have taken an official stand against prop 8, and are running ads to clear up the lies about "gay marriage" being taught (which in California, Marriage in general never has and never will be taught in schools) just shows how full of lies the campaign is for this Proposition.
To people who had issue with this, get your own life and stop trying to live other peoples.
