I respect your reasons for believing that but sadly I don't. I think anyone genuinely fighting a MOJ wouldn't ever get fed up of defending their position. I know I wouldn't. I might be off-hand in my replies but I would make sure I got my point over. You can't afford not to.
I have to agree with Aunt Agatha, Why would he take the time the answer all questions written to him when he has probably answered them a thousand times after the last 30 years? I have read somewhere that if you write to Jeremy he expects you to be familiar with everything.
He is aware that if he distances himself from some of his 'crazy' supporters he would get more credibility. He gets hundreds of letters on a Monthly basis so he can be choosy as to who he commits more time to replying to. If you write to Jeremy and your a female of certain age he might more or less automatically put them in what he calls the 'desperate lonely housewives club' and not invest much time in responding. Allot of women probably think they have some kind of special distant relationship with him when to Jeremy its Just words on a piece of paper he gets all too often with no face to the name.
It would not surprise me if of all the time he spends writing back to people 90% of his effort goes on 10% of his correspondence, those that he feels can make a real difference to his prospects of freedom.
