Yes this. I get the impression that an upper class male demeanour of those times was often tending towards a flamboyant, carefree, foppish, quirky and theatrical demeanour. Perhaps it fell out of favour in the more practical times of the Second World War and beyond. This doesn’t mean they were necessarily more gay but maybe a gay man might have been at home in this environment, if he kept his sexuality very private.

The negative side of this culture was that it was a privileged and rarefied existence, only sustainable amongst an elite who could afford to ignore the real world and be child-like and peculiar if they wanted to be.

This culture seems to live on, to some limited extent, in the British public school educated elite. To an Australian looking on from a distance, people like Boris Johnson and that Reece-Mogs (?) person seem ludicrously foppish and embarrassingly campy and extreme in many ways.
