This is a law requiring employers to discriminate based on gender.
The advocates of this law would probably argue that everyone discriminates all the time, including by gender.
I am on the fence. When I was younger I would have been firmly on the hands off libertarian side. Then I saw what a sham meritocracy can actually be and how much success is based on who you know. The more I saw of the high corporate and financial world the more liberal I became. Do some business consulting work and meritocracy starts to looks like survivorship bias.
So then why still allow all white boards? All Christian boards? All binary gender boards?
Unless maybe it’s just a shrewd political move.
Now they took the next step and made it into law. They completely removed any illusion of a fairness for the next appointment on any currently male only board. Which isn't to say it was fair until now. Probably far from it. Just that now it's unfair with the blessing of a law.
The point is this is not about liberalism. The target isn't to fix the inequality issues. It's a vote grab. Which is why categories with less voting power and more PR issues are largely ignored many times and by many people.
