I was thinking of getting one or two myself. They're not very expensive for something that's probably had a lot of work put in to it.
I don't share Dr. O'Hara's politics, but his writing is of high quality and his work is highly informative. He offers what I would call an 'evidence-based approach' to alternative political analysis. He is the polar opposite of Richard Hall in that respect. I would say that Dr. O'Hara practically invented the field of parapolitics in Britain, certainly parapolitical investigative journalism at any rate.
That gave me thought and I just looked up what Dr. O'Hara might have to say about Thomas Mair, and to my horror I find that he may have granted an interview to the one and same Richard Hall! I suppose I'll have to watch it at some stage. Get the popcorn out.
Anyway, Dr. O'Hara is particularly good on the links between leftist extremism and the state. Dr. O'Hara is an anti-fascist himself, yet he is critical of state-led active anti-fascism.
