During a discussion on same-sex marriage with one of my more liberal friends, I mentioned not wanting the state to encourage self-destructive behavior like homosexuality. My friend asked why I, a libertarian, would want the government to interfere in people’s lives.
Unfortunately this is actually a common libertarian position. So in an attempt to persuade my fellow libertraians, let me outline why I believe all libertarians ought to be opposed to same-sex marriage.
Libertarians believe in limited government. Same sex marriage greatly expands the role of government in peoples’ lives. Ergo, I am opposed to same-sex marriage because it would necessarily entail an expansion of the government just like it has in every country that has embraced same-sex marriage.
Weakening marriage means the state needs to grow to take on the roles the parents once filled. Today that means the state becomes the husband (provider/protector/teacher) in the lives of millions of single-parent homes (which are predominantly female).
When we make sex out to be a private pleasure divorced from any public good (like the production and care and raising of children) then we end up with fewer children (because they are seen as a nuisance) and fewer marriages which provide the most stable environment for the raising of children.
And you know what’s great about properly functioning marriages? The state doesn’t need to interfere with them, so it doesn’t need to grow in order to provide anyone with an imagined “right”.
The family is the fundamental building block of society. And for that reason, all libertarians should be opposed to the legalization of same-sex marriage.
