The American Family Association, known in Michigan largely through their local head Gary Glenn, has been the driving force behind Human Rights Ordinance defeat efforts throughout the state. In a nutshell, the AFA staunchly oppose gay rights.
Now they're trying to lobby Congress on the matter of homosexual marriage. From their website, they are taking a poll to demonstrate what they know to be widespread opposition -- from within their own rigid organization. As the results have been coming in, though, with a bit of trickery on the part of gay rights supporters, the support has been in fact for homosexual marriage.
Take their marriage poll and demonstrate your support of homosexual marriage. These results will be presented to Congress, although I imagine they will think twice once the gathered responses offer a picture counter to what they espouse.
