You see, much of us argue that gay marriage opens the door to the justification of a lifestyle that we disagree with. We fight against gay marriage to ensure that the stigma against this lifestyle remains. After all, as we have seen through the abortion debate, it is never enough for liberals to simply live and let live. They want their view shoved down the throats of everyone.
Mr. Lavandeira has established this point. Miss California (Carrie Prejean) was asked regarding her opinion of gay marriage. She gave the honest answer that she was glad to live in a nation where the states could decide, but as far as she was concerned, she felt marriage should be between a man and a woman. According to Mr. Lavandeira, a judge at the event, this answer cost her the crown.
It is not enough for gay marriage to exist, people like Mr. Lavandeira want it to be accepted and pushed as an appropriate lifestyle, regardless of one's beliefs. For liberals, there is no live and let live - they push a zero-tolerance agenda where their beliefs are pushed as THE beliefs. Anyone who disagrees with them is a neanderthal who "bitterly clings to guns and religion."
It is this attitude that causes us conservatives to want to draw the line as early as possible. The sooner we can draw the line, the more likely we are to reach an acceptable common ground.
