In fifty words or less, explain why there should be a constitutional amendment banning gay marriage. You may not mention God. You may mention kittens, Pop Tarts or a man named Jimmy who sharpens lawnmower blades for a living. If you feel so inclined, you may mention other things as well.
Also, please consider that the purpose of government is to keep its people free and safe, not to decide morality. This we will take as a premise.
Or will we?
