I think it's demonstrably true that there has been in the English speaking west a popular idea, lets say over the last 30 years but maybe becoming a thing even before that, which claims that the only difference between men and woman are the shape of the genitals and who carries the baby. And explicitly denies many of the elements of sex difference many of us would say come out of that. So, for example, people who think this way give short shrift to the idea that gestating a baby, all of the hormonal stuff associated with that, and being the partner capable of breastfeeding, might mean women will be more likely to need/want to take some kind of career break than men.
The most noticible form we find are people who believe that that sport is an equal playing field for males and female, that the only reason there aren't equal numbers of female infanteers, firefighters, or furniture movers, is because of sexism. Or that demand movie fight scenes show tiny women beating the crap out of large men.
People who take this approach tend to think the goal is to see equal numbers of men and women in all employment sectors, social groups, and so on.
I don't think it's unfair to see the development of this way of thinking as part of feminism. Clearly it's not the whole thing, but I really don't know what you'd call it if not a product in the effect of feminist thinking and lobbying on society.
And I think it has in part contributed to setting the stage for gender ideology.
