Alabama State Sen. Del Marsh (R) sees yet another reason to oppose marriage equality: Giving same-sex couples equal rights, he says, is simply too expensive.

“You gotta look at the financial aspect of this as well,” Marsh told an Alabama radio host last week, in an interview flagged by Think Progress. “Let’s face it. If gay marriage is approved, I assume that those types of unions, those people would be entitled to Social Security benefits, insurance. Where does it end?”

Marsh, the President Pro Tempore of his chamber, added that he “wondered if the federal government has looked at the actual costs to the government when they look at an issue like this.”
