Equality of opportunity is a great thing to aspire to, but insisting on equal outcomes is ridiculous. Just because women tend toward some fields while men trend toward others does not mean they're being oppressed.

I'm kind of unorthodox here in that I think what some would deem "equality of outcome" in certain general metrics is actually far more important than "equality of opportunity". If women (or indeed any class of people with particular shared interests), lack sufficient social, political, and economic leverage in society as a whole, then they won't be able to defend themselves from the attempts of men to exploit, control, or oppress them. It's like the balance of power with nation states, except applied to social classes.

Rather than calling this equality of opportunity or equality of outcome (which is a distinction that really doesn't make much sense if you accept that human behavior is deterministic), it makes more sense to call this "equality of power relations" or "relational equality" for short.

But I agree that perfect gender parity in STEM isn't strictly necessary for relational equality to exist, and that feminist activists might be obsessing over it too much. We just shouldn't have open sexist discrimination and bullying happening in laboratories and startups the way it currently is.
