People are asking if Edward Snowden (the NSA leaker) is libertarian. My answer is "probably".
We libertarians have a sort of "gaydar", we can spot fellow libertarians even when they say things that are completely neutral and non-political. Back in the day, I was in the "libertarian-closet", and tried to hide my wacky feelings for limited government. I tried to talk and act like everyone else. However, other libertarians could tell my true self. I never understood how that was possible.
Now that I've gotten older, I've discovered that I've got libradar, too, and can often recognize my fellow wackos. I can't say consciously what makes me feel that Snowden is libertarian, but I get that vibe from him.
