No. He may be a libertarian. If I told you I was a democrat and then donated to republican groups, what would you call me? If my girlfriend publicity supported republicans? At some point you really have to start looking at actions and not words.
My initial rebuke to your argument is simple: Words are extremely cheap. He claims NOW that he is a libertarian but his actions say otherwise. He has also demonstrated a willingness to lie. You can see his comments here where he confirms and then denies that he posted under the account in question: http://www.thedailybeast.com/articles/2016/09/22/palmer-luck...
I don't find any of this "flimsy" or circumstantial. He backed the wrong guy and then backtracked when he got exposed and trump's nastiness started to really come to light.
Again, I almost feel bad for him. But this lying little Trumpkin helped elect trump, and for that, I will not make excuses and try and defend him. He pushed some cool tech but that doesn't put him beyond reproach.
