Huh? Libertarians are the ones fighting for the gay agenda, conservatives oppose it.
Liberals have been lying to libertarians, telling them that homo-everythingism is a "libertarian" position.
Without mentioning in passing that there is sometimes a legitimate and compelling interest in laws against, ee.g., homosexual sodomy, pederastic rape, sexualizing underage minors ( /off pleonasm ), and spreading diseases that otherwise would not be spreading much or at all.
Society has a compelling interest in suppressing vendetta, manslaughter, and homosexual sodomy.
