The only 'fucking's are used in the sub-headings, not in the body of the text. To me, this makes emphatic sense within the context and the use is consistent, not random. I don't see it as trying to evoke hipness or edginess, nor as annoying or adolescent - I consider the writing produced by CJ to be pretty grown up already. Fair enough your reaction and you are fully entitled to it, I just don't agree with the tone of censorship re. CJ's writing, and am saying so.
