Gay marriage was recently legalized across the entire United States, and I couldn't be happier.
Me, I personally do not benefit or care, as I have no interest in a gay marriage for myself. However, for those who were gay married or wanted one, glad you all can enjoy that across the nation now.
The reason I'm happy is because the argument used to strike down all existing bans is the logic that everyone is entitled to life, liberty, and pursuit of happiness, and that cannot be abrogated without due process of law, and the only barrier up to this point has been a bunch of people bitching about how marriage should be defined as a union between a man and a woman.
Why? Discounting religion (which has no place in laws governing people of all faiths, and no faith in a country that has no established church) and traditional societal standards (which can change and are thus meaningless), there are no good arguments I can come up with legally to bar gay marriage, and since my rights are not being infringed and these people are free to pursue their happiness now, I'm all for it.
So, gay couples across America, consider this post my congratulations on your now nationwide legal nuptials.
