I left the RAF some 10 years ago and, at that point, we were generally very well in touch with 21st century society. It seems like the general is probably trying to address his own personal weaknesses, not those of the 100+ thousand personnel who will serve under him and (generally) get along just fine.
So, not being promoted for failing to adopt a positively discriminative stance? I bet the Air Sec is already tearing her hair out at the thought of the pile of casework coming her way.
