This libertarian seems to think so and after I sift the rhetoric from the reality, I have a tendency to agree.
The one thing that I agree with the gay agenda on is that by the principle of subsidiarity, the government has no place in the home. Not just the bedroom, but the home. And by no place, I mean no place at all- giving tax breaks to some households over other households due to a contract that bears no relation to traditional, sacramental marriage whatsoever is discrimination. The concept of consent is equally ridiculous; it always turns eventually into people bringing the problems of the home into court with the silliness that is the concept of divorce- a concept that would entirely go away if we'd just do away with ALL the legal protections for marriage.
On this day when we celebrate the apparently antiquated and anachronistic concept of a Father, a role that almost no man under the age of 70 seems to be able to fulfill anymore in this age of feminism where all men are evil, I see no role left for marriage at all.
The only reason left to preserve traditional marriage, is if we want to bring back the concept of fatherhood- and we all know that the liberals are completely against *anything* to do with a patriarchy.
