The family unit is the bedrock of a stable society?

Without necessarily tying this to the gay marriage issue, the above statement is by and large true. It is the sole environment that has historically allowed children to be raised well with some degree of emotional and financial stability. And of course there are the economic and personal benefits of people living together as couples that IMO would be extremely difficult to replicate with any other sort of communal living arrangement.

"Gay marriage is breaking up the family unit!"
*cheats on wife with another woman, marriage breaks up*

Overcompensation of the part of the occasional Republican candidate aside, there is a serious class issue here, in that the regions most perceptive to the religious and socially conservative Right tend to be those experiencing the highest levels of social breakdown in terms of the family unit, and they also tend to be the poorest. In America, your "White Trash", or the UK, the benefit-dependent underclass.
