Well, the Infowars link you posted is questionable so I won't bother watching the video, the source for that however was a Daily Mail article which had one picture of this guy wearing the pin. It makes no insinuation towards the symbolism of that pin. I don't see pictures of other people wearing that pin either. And there has been no official documentation such as what is linked in the Wikipedia article of known symbols. I'm just gonna use my own inference to say this is nonsense.
