An outsiders perspective......
When I went through IOT we studied supposedly great RAF wartime leaders, like Bader and Gibson. However, in both these particular cases there were two distinct camps - the love em and hate em. Baders groundcrew were supposedly overjoyed when he was shot down, while Gibsons groundcrew may well have killed his dog. Leadership, especially during wartime, is not a popularity contest, but there is a difference between leadership and dictatorship. There are also considerations in a (largely) peacetime RAF, such as career development, that didn't apply in WW2 which may call for a less forceful approach.
I don't know this particular individual (JG?) but opinions seem to be polarized into two camps in his case - once again you seem to either like/respect/admire him or not, with little or no middle ground. So, at least on that basis, he is similar to both Bader and Gibson.
Talon - I thought you weren't going to read this site again?
