On the contrary, I know quite a few men like Frank who are old school 'Gentlemen' and expect ladies to act in a Ladylike manner. They just do not 'get it' that their language and behaviour is considered condescending and paternalistic by modern women, especially as their wives (if any), mothers, sisters and many of their elderly female contemporaries consider them to be perfect gentlemen and butter them up. I am not surprised that the 'ladies' who attend classes with Frank are very friendly towards him. He is a widower, fit, has a full head of hair, speaks fondly of his daughters and Grandaughters, owns his own house and obviously has a bob or two.
We are wasting our time trying to convert Frank to a modern man, he does little harm and much good. Better to concentrate our efforts on the really bad guys.
