They have their own mind virus which makes them think that meek, innocent, naive hyperfeminity is the only valid femininity. They watch anime[^1] and terribly written women in film. Both of which infantilize women. And they watch women get dominated by men in porn.
[^1]: Anime fans, miss me with your examples of "badass" women in anime. They all still look like little girls 90% of the time.
The concept of femininity in these boys' heads is completely divorced from what it actually means to be a woman. To be a human being. They want all women to dress in school girl outfits, short skirts, or satin dresses. Women who should spend 100% of their time trying to please their husband, a word that historically means "a man who manages a property". They see women as sexy property.
As a bonus, they all want "trad wives" and yet they vote for politicians that make it impossible to survive on a single income unless they want to live in a trailer park.
