As there are no rational answers to this question: 'What harm will befall you personally by same sex marriage equality?' those with the capability for rational thought must dismiss objections to same sex marriage equality as invalid.
If objections are invalid there remains no rational reason to oppose same sex marriage equality.
Those still posing objections have yet to make their case. So, we must then presume that those still posing objections are just objecting to homosexuality altogether.
As homosexuality is a personal choice and has no adverse affects on the institution of marriage or personal lives and is not criminal behavior, those objecting must be seen for what they are: bigots and small minded haters without the capacity for rationality in this area.
Why then are they potent enough to throw roadblocks up in the way of liberty? Do they claim to be Americans? What then about America do they love? It certainly isn't the liberty and freedom we have here.
It's as if we are back in the 1960s arguing for the basic freedoms for African Americans. No rational objections were posed then, and, as a result of the protections of law all Americans now enjoy, we have a stronger nation. We could not, nor should we, hold any moral authority while we allow blatant discrimination based on immutable characteristics like skin color or sexual orientation.
