Well, this was the point I raised, that if I'd walked around the office saying 'All Women are Whores', or 'All Muslims are Terrorists', I'd have been out on my ear, but 'All men are born liars' apparently fell into a different category according to my Coordinator, who was male, and had been friends with my line manager for well over a decade.
Worst part is that no-one wants to touch situations like that, if you get a female member of staff being sexually harassed, at least in the environments I've worked in, there's a whole support and representation framework available to them, whereas a male member of staff in a similar position has considerably less support to hand.
Discrimination is raceless, colourless, genderless and sexualityless (if there's such a word), what confuses me is why some people seem to struggle with such a simple concept.
