I wouldn’t waste much time on 'Hal' Turner.
He is a man who has talked about the need to assassinate Members of Congress and Judges. While skirting just inside the boundary of the law “that would be illegal but I wouldn’t mind if” or “Someone should.”
As well he’s a more than garden variety anti-Semite believing that “Christians should be rounding up Jews and killing them here in America” and certainly it shouldn't be surprising that he is a Holocaust denier.
