I have heard a few stories lately of hollywood celebrities who have decided to wait until gay marriage is legal to get married themselves. The latest is Full House star Jodie Sweetin who was proposed to this last week by her long time boyfriend and "baby dady" to their child. They have not set a date because they are waiting for gay marriage first - no matter how long it takes. This supposedly passive aggressive form of protest is not one I would see being all that effective. Why? Because, who cares if a celebrity gets married or not. It isn't necessarily hurting society as a whole for this to happen.
Generally protests are designed to disrupt economic activities or political movement in order to encourage change through disruption or economic injury. But this? Think of the gay wedding planners who won't be getting paid to put on her wedding? They are the one's getting hurt, not society.
I do find this to be a very odd form of protest. I am not sure there is much value in doing so. Nevertheless, to each his own in sharing their voice.
