I do believe that roughly speaking, for an equal amount of work, black and white people should have similar salaries, for example. Something that is not the case today.
This is a disparity that can't be explained away by choice, or innate supremacy, but is instead à result of inequality of opportunity. So you have to fix the opportunity gap.
I do have an issue with the imbalance in nursing. That's because there is a strong stigma against men in nursing and men in nursing often suffer strong discrimination. In a society where these stigmas don't exist but men in general decide not to become nurses, that's fine.
Same in tech. There are stigmas and discrimination against women in tech at every level. For example, different countries have massively different amounts of women in engineering. Women in countries where this amount is lower often report discrimination. So this is clearly not a question of choice, and is thus a gap in opportunities led by sexism.
It would be nice if you wouldn't assume the absolute worst possible interpretation of the argument of your interlocutor. This is against HN's guideline and generally increases the amount of noise. It's also quite rude.
