There’s a fat little squire in all of us ... Orwell believed that the art of Donald McGill served as a release valve in a society that was otherwise virtuous and repressed
Ie. Society is men, and women are other.
He spectacularly misses the point doesn't he. It's not that we want to spoil fun, or that we're repressed or lecturing. It's that we don't like being objectified, having sexually explicit pictures of just one sex in the pages of a newspaper is clearly wrong, that even if there's no proof it contributes to rape culture (interesting that he's very careful with dates on his stats.. I wonder if that's just preciseness, or that he's cherry picking?), it definitely does contribute to a hostile, sexualised environment for women and girls that boys and men have no experience of.
In fact, there you go. I'll stop complaining about page 3, if every other day it's a bloke in tiny pants. That way there's a chance that 15 year old boys will get a dose of the ridicule 15 year old girls get, and so gain some empathy and understanding into why it's unpleasant, and perhaps not grow into such uncaring men.
