And why not - it really is the only argument they have, one that never has been supported by facts:
Again, Maine's equal marriage law does not affect the standards set by the Maine Department of Education. Local school boards determine whether marriage - be it between straight or gay couples - is taught in school, or not. Some schools in Maine already teach about same-sex marriage - before LD 1020 was passed this spring.
Of course, most 8th graders have questions about sex - their hormones are raging as they enter puberty. It is natural for them to want to know about it, and in some cases, these kids are interested in homosexuality - it happens, as Benoit Denetiz-Lewis, writing in the NYTimes Magazine a few weeks back, made clear in coming out in middle school
Update: This is really just so over the top that it's beyond belief. In an email, Marc Mutty states:
Our most recent ad, called "Give Me A Break," uses a teacher's very own words to prove our point even more dramatically. National Public Radio interviewed Deb Allen, a Massachusetts sex education teacher, on the topic of how some teachers have responded to the teaching of sex education following the legalization of gay marriage in Massachusetts.
You'll note that the teacher in the NPR interview is in the ad is cited as an "8th grade teacher," not the sex ed teacher she is. No wonder she answers questions about gay sex "thoroughly and explicitly" - it's her job to do so.
