Those who comment on 'overt' crew members are dare i say it, commenting on Campness and flamboyancy. Whilst some 'gays' can lay it on thick, for many they are just naturally camp and for others it is just their personality. To say they are unprofessional is border line homophobic.
Making sexual suggestions is bang out of order but lets face it they are the minority and heterosexuals are just as bad!
