Sexual perverts (gays) already have the exact same marriage rights as anyone else. They can marry any person of the opposite sex that will have them. Why do they need special rights?
Marriage is now an entitlement. It not longer going to be seen as a gendericist institution.
Liberals think if you can’t get rid of it, change it so every one can get married. They’re right - if its an entitlement, keeping gays by virtue of mere accident of biology from marrying each other is the very epitome of unfairness.
And they’ve found Americans’ Achilles Heel: we take pride in considering ourselves to be fair.
