It wasn't an erroneous claim because what constitutes a human's "right" is a completely subjective term. I think people should have the right to be protected by the government from violent crime, or that they have the right not to be spied on. I don't think they have the right to get legal bonuses for finding a girlfriend or boyfriend. It's basic libertarian philosophy of a small government having input only on important matters, not trivial stuff. I don't see gay marriage as an important matter. In fact, it's frequently used in America as a debate point by the Democrats and Republicans merely to disguise the fact that both parties are almost identical and wish to rule the country in the same way.
