Hello Karen. Gender equality (or inequality) is certainly not confined to pay. It comes in all manner of guises and disguises. In the 1960's I ran two female football teams. The reason for orgainising two teams was that (in those days) women were not allowed to compete against the men, so the two teams had to play against each other. There were no other female teams to compete against. Noboby got paid and there was just as much 'support' for the women as there was for the men( I suspect that was for the novelty value of the spectacle). Perhaps it's my own perception but in those days there seemed to be very little fouling and certainly no falling down without good reason. Also, at work, I was an honorary member of a 'women's group' who were working towards righting the wrongs of gender inequality. I think they found it useful to have a male advocate to speak (and write) openly about discrimination alongside them on their behalf.
I could go on-and on about this subject because, in essence, the basic principles and practice of inequality are the same as all the other types of bullying there are in the world of human interaction.
Best wishes
Bill
