If you've read KW's Diaries, you don't need to read Back Drops - which is less a real diary than a version of KW's chat show act put into the form of a diary: certain incidents did actually happen but not as described in Back Drops, which attempts to give a spurious 'one year in the life of' account.
Also: the KW represented in Back Drops is very much one for public consumption - no bitchy stories about colleagues, no misanthropy, no confessions of sexual shame and loneliness. Hence: 'sanitised'.
The publication of KW's REAL Diaries upset a lot of people (possibly you included), as it revealed a man who was frequently cruel, sometimes racist, right wing and (self) oppressed. I know at least one person who now refuses to watch KW's films on the basis of what he learned from those diaries. Personally, I liked KW more for having read them, as they showed him to be vulnerable and contradictory: in short, a real person. People who object to his frequent references to 'Negroes' and the 'swamping ' of London with 'coloured' immigrants ignore his donation to anit-apartheid causes 'because I abhor the racist state.'
You probably don't read the Daily Mail, so you will have missed this article, which refers to the fate of the original Orton Diaries:

As to the casting of the boys in Loot: Orton was asking a lot of his actors, here - Hal and Dennis are young men (ideally in their late teens, or very early twenties), yet they do not use the kind of language spoken by most young men of their background and to carry off Orton's lines requires a technique well beyond the reach of most young actors. I've never seen the pair played well and I've seen many productions of this play. The other big problem that Orton faced (though it is not such a problem now) was his own requirement that the two boys be believably bisexual ('The boys in Manchester are poor', he wrote of the first 'proper' production, 'Clean as a whistle sexually.You can't imagine them having each other, or Fay, or anyone....'). Though he was apparently pleased with Kenneth Cranham's performance as Hal in the West End production, he was not so enamoured of Simon Ward as Dennis.
Not sure what you mean by my 'passive aggressive' stance, but I hope the above provides interesting back-up to my assertions.
