Joyce Fegan: Deconstructing a sexist culture is heavy work and we need more than women to do the lifting

In a world where we ask such ridiculous things of women like to not go out, to not let their hair down, to not venture out alone after dark, is it too much to ask non-offending males to call out the sexist jokes of their mates, the 'banter' in the locker room and the ridicule of anyone who confronts their 'humour'?

Tributes left for 28-year-old school teacher Sabina Nessa at Pegler Square in Kidbrooke, south London.

It's the jokes. It’s the banter. It’s turning a blind eye. It’s the cat-calling. And it is the accepted ridicule of anyone who confronts any of the latter: ‘God, you’ve no sense of humour’; ‘You’re so sensitive’; ‘You’re a ‘ball breaker’ ’; ‘You’re such a bra-burner’; ‘What a snowflake’; ‘Can you not take a compliment?’

While these ‘jokes’ are being shared, and those who find them offensive are being rebuked, women and girls are being assaulted, raped, and murdered.
