In addition to lying about guns themselves, the "experts" love lying about the Second Amendment. And no, they are not idiotic, they are liars; they know damn well what they are saying isn't true. Remember the civic ignoramus who wrote that giant strawman of libertarianism that both of us wrote responses to? He's got an equally fallacious article on this subject as well. I wrote a nasty comment refuting it, which he deleted (along with all my other comments on his entire website, even the polite ones) the last time he bothered to update it. Feel free to leave a response, but just know that he will never engage with it, much less change his mind.
Sometimes the only purpose of engaging with such nonsense is to show others that they are not alone in seeing the nonsense.
