In a nutshell he calls Jay a liar. He justifies this by comparing 3 versions of the same event (ie the justifiable punch in the mouth Sibrel got), namely;
- Buzz recounting how he was interviewed by a Japanese TV company in 'Magnificent Desolation'
- Sibrel claiming he was merely an invited guest of that company in his work of fiction passing as an autobiography
- Jay's assertion that Sibrel was the TV company, using subterfuge to gain access to Aldrin, just like he did other astronauts
Of course Sibrel would never fabricate things, cherry pick facts and twist the truth in order to publicise his grift and make his story sit better with his marks. Doesn't have a history of that at all. No sir.
