The systematic interpretation of this law is that it is legal to moderately discriminate in the favor of women when they apply for a position (school, work) that has a male majority, while it is illegal to discriminate in the favor of men when they apply for a position that has a female majority.

Examples of male-majority situations where this is applied is CEO or board positions in publicly-owned companies or engineering school, while examples of female-majority situations where this cannot be applied is veterinarian or medical school.

I know this from film sets: I happend to be in crews, that were so diverse, that the only overlap in the end was that all of us somehow liked film. These were incredibly interesting and motivating crews, with a ton of creative ideas, willingness to go the extra length etc.

The worst crews I saw, were the ones where you had departments that had creepily aligned departments, that defined themselves by drawing a border to other departments. E.g. a light crew consisting completely out of white “dudes” all with the same ideas, jokes and taste, similar age etc. They did good work, but once they outnumbered the rest, the open discourse/exchange of ideas on set suffered.

But there are other ways to approach, and possibly fix, this problem. One would be increasing the reach, e.g. you could investigate if your job ads reach mostly women and instead advertise on some male-heavy media as well. Another would be fixing the underlying biases and misconceptions of the job (e.g. that teaching is a female job or that men that want to spend time with children are likely pedophiles) - though that one is obviously harder to do, you need society-wide influence. Or maybe you'd figure out that it's just the way it is, and there is a huge gender (or some other characteristic) imbalance in the whole pipeline (i.e. not just the applicants for the job, but already when people are applying to universities for the appropriate field of study) (in which case positive discrimination would mean you'd have to lower the bar to an unacceptable degree), which might be OK as well.

It's also odd that talk about the value of different perspectives and diversity can disappear as soon as some women create women-only workspaces for themselves.

It's examples like this that make me unfriendly to feminism. Equality of opportunity is a worthy goal, but either you support genuine diversity or you don't.
