Hold on. What happened to your original claim that, by not voting, you were sending a stronger signal of your libertarian views than you would by showing up and voting for libertarian candidates? Did you concede that point, or are you still holding onto it, or what?
Please pardon me if this seems obsessive-compulsive, but there's an interesting pathological form of "debate" where someone keeps throwing arguments out, ignoring any refutations, then declares victory. Of course I'm not accusing you of this -- such an accusation would be very flimsy -- but it's always something to watch out for.
