Why is BL written for women?

Kinda answering my own question but oh well
Researcher Mizoguchi Akiko said this:
In Japan if a woman was seen buying and reading straight explicit material she would be seen as easy or a ‘’slut’’ if she would have been seen reading lesbian material people would think she’s lesbian and she would be harassed, however if a woman was seen reading BL then the man around her would think nothing of it. This gave women a safe space to explore and talk about their sexuality without suspecting socialized pressure hence the popularisation of BL cafes. And naturally, as more women started reading BL, the BL genre became catered towards women. Therefore the relationships in BL are not meant to accurately represent real Mlm relationships. This is also why the argument that Bl inherently fetishizes Mlm bc is written for women is flawed. It Becomes fetishizing if a woman takes the idea she reads in bl like ‘seme or uke’ and pushes them on to real gay men

Sorry if there are any grammatical mistakes.
