The gay and lesbian groups are gaming everything in sight to advance their cause. Lambda legal Foundation has a lot of very smart lawyers and their strategy seems to be to challenge everything and anything. I dont think an action against Grove City will succeed, but it will garner them publicity and burn up a lot of Grove Citys budget in legal fees.
I am disappointed that no one seems to be recognizing that a Federal Constitutional Amendment will be necessary. Public opinion polling seems to show an essentially schizophrenic set of attitudes. From the same sample you can get both support for state actions (constitutional amendments at the state level) by a slight majority, and far less than a majority supporting for a Federal Constitutional Amendment. I think this shows where people could use a bit of education. There are many weaknesses in the state amendments that have been passed. The Federal Defense of Marriage Act (DOMA) will be repealed under Democratic majorities in Congress and at the request of Obama. Then you will have a wave of gay and lesbian couples flocking to the states where it is legal and then returning home to jam up the local legal picture with suits 9 ways from Sunday.
It has to be a Federal Constitutional Amendment prohibiting gay marriage and it needs to be soon. Wake up out there!
