I don't know, maybe feminism means something different in Poland, but here in the US women have already had equal rights for a while, and now feminism means getting special rights men don't have. The movement is fundamentally dishonest with most of their shock statistics. An example would be how they say that women are paid less, and cast that as oppression, but they don't say that's actually because women on average choose to work less hours, and tend to choose different, less dangerous, jobs than men. That's fine for women to make those decisions, but it is not fine for feminists to pretend women are being unjustly treated when they receive less pay for less work, and safer work.
One of the reasons why men make more is that even women with jobs still expect a man to provide for them, and be the primary breadwinner. It's their instinct. For men a good paying job is a requirement for a woman to even consider having a family with them. Most men don't put that requirement on a woman, so there's way more motivation for men to try their hardest to get the highest paying job they can.
So 50% women workers earning 50% of the money overall actually means not allowing equal opportunity, and preferring women over men, since they're not equally motivated to make the most money. In the end women cause men to make more than them, feminists get upset about it, are dishonest about its causes, and blame men. After that they demand policies are put in place trying to stop men from making more money, and then as a result women get upset that they can't find a man who makes more than them, and blame the men too. Men aren't the root cause in that situation.
