What good reason is there NOT to wear one?
The only good reason that I know of is that they are hot in the summer. Personally, that is an inconvenience that I am prepared to put up with.
that bit of tacit oneness with the most professional flying organisation in the world
This is not the first time that Genghis has made this sort of bombastic reference to the RAF.
Which air force (or non-air force company, unit or association, come to that) is "the most professional flying organisation in the world" is of course highly subjective; and assuming that the RAF has no competition for that title is
just plain stupid.
England has many great traditions of which it may rightly be proud; but the reputation of presumptious arrogance isn't something that anyone with any sense would want to perpetuate. It's time to move on (the Empire is no more, and thank God for that!).
Please, let us have no more of this sort of mindless parochialism.
