I hate to say this, but you cannot come together in "love" to deny equal rights to a group of people and not be hiding a swastika tattoo.
The only arguement that hasn't involved their distress over the possiblity of their own butts being pirated, is the one of freedom of religion. The folks depicted here seem to believe that freedom of religion means that only the religious have freedoms. The fight to clarify "seperation of church and state" is slowly being brought about by the religious right, and they will lose, thus making the issue a matter of discriminatory dogma that will make hypocrites out of many. In the end, gays will get what they want, and the religious will lose their Constitutionally false muscle.
Teachers do not teach about marriage, but they do discuss current events and because of the Protect Marriage crowd, it has become an item of discussion. Raising your kids to tell others that God says they're wrong will inevitably lead them to the "well, why don't we just make them for their own good" question. Parents not able to see the little mustaches growing or unwilling to give them a back-peddling shave can rest well with the understanding that after your kids go to jail for beating up a homosexual classmate, then they will really get to see what the hype is all about, minus the love and lubricant.
Jesse Jackson should sue the hell out of them for copyright infringement...
EDIT: And if it is a joke, they should have had the good sense to make themselves LOOK the part of the closet Nazis they are. Otherwise you rile up the 30-something, self-righteous Berkeley faux-hippies like ME!!!
