There were a few crusty old bourgeois socialists amongst my uni lecturers but they were pretty chilled out and at the end of the day the primary aim of many of their pupils was to get out into the capitalist world and rake in some serious money so they could hardly participate in that and maintain a pretence of authenticity.
Some of my school teachers were old-tie, tally-ho what what, damn good thrashing, showers in the pavillion and down to Monty's for trebles all round types but they were respectful of differing views too.
