There are 19 states in which you can marry your cousin legally. Gays can marry in five states. There’s overlap in Vermont and Massachusetts which must mean they really don’t give a shit about what you do in the bedroom.
Oh, there’s a total of 34 states in which cousin marriages are legally recognized. Take a look at this handy map made by Mac McClelland at Mother Jones.
The real question: May gay cousins marry? (By the way, if the notion that cousins may marry but gays and lesbians may not doesn’t make you want to kick a baby in its soft spot, you’re not really human.)
