So:
A critical part of making men and women equal is by balancing the sexual-social rights/duties of both sexes. The harsh truth is that if you want to live in equality - and some people do not - you need to address imbalances that you might think are otherwise natural.
As they say: the law gives both the rich and the poor man the freedom to sleep under a bridge. Adapt it for feminism: the law gives both man and woman the freedom to give birth to a child. Our society imposes demands on women that it simply doesn't impose on men. A socialist feminist approach has the practical and intellectual muscle that liberal feminism doesn't to overcome these demands.*
Constructing equality comes in two parts:
The first, and easiest, is to provide for women the same freedom that men have - the freedom to ignore the immediate biological demands of life. Cheap tampons (or whatever you people put to stop it bleeding, idk), free and easily available birth control, et cetera et cetera. This is kind of why it's frustrating when people post pictures of the "female equivalent of a male product that is exactly the same but more expensive." Cosmetics aren't a biological demand. The tampon tax is a good example of a sexist and obviously wrong policy that we could stop tomorrow. Our society needs to stop obsessing about what women do with their sexual lives. Part of living a fulfilling and satisfying social life is your sexual life. Men's sexual lives are almost entirely unregulated and women should have the same freedom too.
So that's all well and good, but it gets more complicated from there - most young-generation males probably already believe the above anyway. The other aspect is work, and that's where liberal feminism falls flat and marxist feminism has real answers, because of their differing perspectives on work. Liberalism has a narrow-approach to defining what work is - selling labour in exchange for money from an employer. But on top of all the hours worked in a week at a workplace, there's also work at home - housework - and work with children. It's impossible to compensate people for this because it can't be recorded, but it is obviously a form of labour. The answer is to communalise work that is traditionally unpaid for women.
Free communal launderettes, subsidised communal canteens or food courts, free or near-free childcare facilities and programs. One success of the left-wing government in this country was the free childcare program that allowed single mothers to send their kids to childcare so that they could go to work, have an economic life, and generally free themselves of the biological demands of being a woman (i.e. child-rearing.) Obviously the right-wing government defunded this program as soon as they got into office (tfw when Conservatives love "the family" but children are always the first target of their fiscal cuts
)
A socialist society in which the working class collectively own the means of production offers actual equality. Women and men can share the economic and social decision making processes at a local level. Liberal feminism on the other hand makes no sense: just watch as you vote a woman into office who will then go and defund your health services, slash the regulations that force your employer to treat you like a human, and send your sons and daughters to die on foreign soil for the sake of a pipeline.
* Society also imposes some demands on men that it doesn't on women, and those should be equalised too.
That's my problem with intersectional-liberal feminism. By focusing on the experiences of granularised groups, attention is drawn away from the structures which cause inequality and exploitation, and towards the subject demands of the people who experience it. But that inequality and exploitation will remain until the structure is torn down.
