If you believe this guy represents libertarians then you probably also believe that Fred Phelps represents Christians. And that makes you a disingenuous doucher or seriously fucked in the head. Take your pick.
My support is simple logic and reasonableness, both of which you obviously lack. Libertarians believe in limited government and limited restrictrictions on individual liberty. They do not believe in no government and no restrictions. It's a matter of simple logic and reasonableness to conclude that laws against animal torture do not run afoul of libertarian ideals. To suggest otherwise is ludicrous hyperbole at best (USCitizen) and pure intellectual dishonesty at worst (You). But of course you know this so you throw out the bullshit red herring that I somehow need to validate what I know to be logical and reasonable with a written opinion of another. You fail.
