He's a hack scientist who has published and claimed numerous things that have later been proven false - that he created email, that GMO soybeans cause cancer, etc - which he has used to sue for libel and defamation of character. Ironically this 'proponent of free speech' was backed by Peter Thiel in a suit against Gawker that was concurrent with the Hulk Hogan suit.
He's a republican and is trying to reposition himself as a populist for the GOP senate primaries in Massachusetts, with the hope of facing off against Elizabeth Warren in 2018.
He's little more than an opportunistic vulture who saw this as an opportunity to perhaps curry favor with the Trump supporters in Massachusetts - of which there are enough to decide the republican primary.
He also believes that pretty much all groups - KKK, BLM, Antifa, you name it - are funded by 'the Establishment' as a 'distraction from economic problems.'
He was, for all intents and purposes, the "opening act" of the rally, which originally was to include notable white supremacists Augustus Sol Invictus, Gavin McInnes, Joe Biggs, and Kyle Chapman, among others. Two of those did not come - Invictus and McInnes - and the rally, poorly-organized and poorly-attended as it was, fell apart before Biggs or Chapman were able to speak.
But hey, why do any research into things when you can just trust things posted on YouTube!
Again, how does that make him a "white supremacist"? ---
