Alex,
Some of your points are well-taken. I get the sense from the interview, as well as his past interviews, that the whole 'anarchist' thing is a response he uses when he feels he is being asked silly, unanswerable questions. Like 'explain your genius', 'how do you take a masterpiece', you get the gist. How does one answer these sorts of interview questions without sounding silly in response? I have a feeling he was having a bit of fun with these sorts of interviews. By contrast, you should watch the interview he gave in Robert Capa PBS' documentary, where his answers are poignant and quite emotional. The difference in subjects (talking about his friend Capa as opposed to talking about himself) seems to have contributed to the level of seriousness with which he treated the questions. In some ways, you might argue, he takes himself far less seriously by the way he answers these questions.
Winogrand once said that there are no photos when he is changing film. Sarcastic, sardonic, arrogant, perhaps ? Yes. But also true in a sense. Imagine the same sort of silly questions Winogrand no doubt answered in every interview. Which 28mm lens did you use, what did you think of the bokeh, how was the the sharpness of your lens at the edges, how did you create that classic shot .... 😉
It should be noted that Magnum photographers to this day are very loyal to HCB as a photographer and mentor. Even those legends with substantial bodies of work themselves, like Erwitt, Koudelka, Depardon etc. And they would be the best judge of what a good photographer and mentor would look like 😉
By contrast, you will not find the same loyalty or regard by Magnum photographers for Abbas, Salgado or Peress. Not because they are lesser photographers, but because they did not have the same ability to mentor that HCB, Capa and Chim did.
Which is to say, you need not like the man. But clearly a lot of his colleagues do. I'm sure he did not earn this loyalty by luck. Nor did he earn his seminal inspirational role for other photographers of acclaim by chance. If that were the case, there would be a lot more HCBs. Clearly there is not.
cheers
