Until very recently the social contract ensured that people followed social conventions and the law. Men didn't enter women's single sex spaces, it was accepted that children should be safeguarded from age inappropriate sexual issues etc. Women felt free to challenge a man invading a space where they were undressing, naked, using the toilet etc. All evolved from Victorian times as tools to allow women to play a full part in society.
Now we appear to have a new brand of Victorians - mainly men but as we sometimes see on here, women too - who openly argue that women have no rights to privacy, dignity or safety from unknown men or single sex sport etc.
It's a very regressive approach that dismisses the needs and rights of a range of protected / vulnerable groups, but the new male supremacist Victorians (male & female) are relentless in their pursuit of removing women's rights to boundaries, safety, sport and the rest.
