I know many Clampers. E Clampus Vitus (E.C.V.) Similar to the
@Snakegang. They're an old drinking frat of loggers,miners,bikers and blue collar maniacs.
He is a Clamper... to my knowledge it's just a brotherhood of white guys / 81 supporters. But then again I don't know much or claim to. I just know he seems very vigilant these days, & has a much different outlook on things from what I can tell.
Plus he lost like 95 pounds & looks a hell of a lot healthier, so I am happy for him in that sense.
Clampers are pretty much a drinking fraternity that dress & look like a motorcycle club, in particular the look they mimic is very much HA-ish with the red & white everything they got going.
