There are many ways divorce affects those not directly involved, but you're just checking he perimeter of my argument for weaknesses, so I'll stop there.
I think many black people get offended when gays compare themselves to black-suffrage, which is why so many Blacks voted against ssm right after voting for Obama in the 2008 election.
Also, I prefer government out of my personnel life. Its ridiculous how you want the government to have little to no gun control but literally want them to coach everyone on how to conduct their marriages. How about you be a conservative and tell the government to shove it.
The other side of the coin is, if one state's marriage license is good in every state, then my CCW should also be good in every state.
A little consistency is all I ask for.
