Thomas Weber, a professor of history and international affairs, argues that "Brenner's book lies well outside academic mainstream. It is mostly celebrated either by the extreme left and by the neo-Nazi right";[1] among others, the Institute for Historical Review – defined by the Southern Poverty Law Center as an extremist neo-Nazi organisation promoting Holocaust denial[6] – has cited the book in their research.[7] However, Brenner has criticised and condemned the use of his work by neo-Nazi Holocaust deniers.[1]
