From a list of "far-reaching, devastating and pernicious cultural consequences" of Illinois legalizing same-sex marriage

Public schools will be hiring teachers who are in legal “homosexual marriages.” These teachers will put photos of their homosexual spouses on their desks and talk about their homosexual spouses to their students. Such images and ideas coming from teachers whom children love and admire will powerfully shape the feelings and beliefs of young boys and girls, particularly when such images and ideas are reinforced countless times in other cultural contexts. Such images and ideas will undermine what is being taught at home.

Some will argue that schools are already hiring teachers in homosexual relationships, so the legalization of same-sex marriage won’t change anything. They are only partly correct. Although schools are, unfortunately, already hiring teachers in homosexual relationships, once the government recognizes homosexual unions as marriages, administrators and school boards—particularly in elementary schools—will have the social stigma that makes them reluctant to hire teachers in homosexual unions knocked out from under them. And this, of course, is the chief motivation for homosexuals to pursue same-sex marriage when they already have all the benefits and privileges of marriage through Illinois’ civil union law.
