Tau Beta Pi is an engineering honor society with no Illuminati-style secret agenda. The only silliness associated with it is any concern over the "initiation rites and rituals".
I did point out that he was a Nazi, and was attempting to shine light on the fact that he was connected to people in high places via a society that has initiation rites and rituals (what you are referring to as a college club).
And the overwhelming majority of societies with initiation rights and rituals are not world-controlling cabals. Turns out people just like having rituals (and afterparties).
Where did I say they were a cabal that controlled the world? There are many famous and influential people that are a member of that society, and they swear oaths and go through initiation rituals. Believe whatever you'd like!
