The problem isn't gay marriage, the problem is the total government control over the individual and his property. The problem is redistributive theft at the point of a government gun. So yes, extending this theft to the gay community is not desirable. It shouldn't exist for heterosexual couples either. Extending stolen goods to anyone in the monicker of 'entitlements' is theft.
But the problem is NOT that the gays are married, the problem is the existence of the total state control over the individual and his property.
