If that's the only way to end the backwards conservatism, I doubt it's gonna happen. Once you admit that you are agnostic or bisexual you have no chance of making it into office. It doesn't matter how good your ideas are, the deck is automatically stacked against you because a lot of Americans are so full of their own prejudices that they will dismiss any good idea that's presented to them because they don't like the source. If all it takes to discredit your ideas is a listing of your personal flaws or the fact that you are different than "the perfect American" (i.e., straight, Christian, and have an overwhelming desire to make tons of money), then nobody's ideas have any merit.
