That's not particular to conservative media; it's the same tactic used to convince whole swaths of the population that the rich, the white, sexists, racists, jingoists, big corporations, government, etc. are keeping you down.
Leveling it at only one side of a debate is falling into the trap polemicists set up. They all do this, from every angle and via all means possible. It's just propaganda, and one insidious aspect of it is that they convince people only the other side engages in it.
If you want to be truly libertarian, guys, you also have to embrace open borders, support non-interventionist foreign policy, and desire that drug prohibitions cease. Defending gun rights and complaining about taxes and welfare is just a tiny part of the package. You can still oppose state-sanctioned gay marriage if you want, but only to the extent that you oppose government involvement in any kind of marriage.
As I am a long-time libertard, the people who talk about freedom after watching Fox News make me laugh. They fill their heads with mass-media talking points all day, meet with like-minded people to create an echo chamber for the ideas they were force-fed, then worry about having adequate self-determination.
