The thing is that the way in which people manifest their sexual liberation is being blamed for these expectations and social restrictions. And a link is often made between the two. If you enjoy a certain type of thing, you can be thought of as being the cause of these issues or can be seen as enjoying them being a thing.
What manifestations are you talking about, here? This tangent
started out discussing erotica, but I think we both know well enough that it's not "sexually liberated" women making, producing and selling "titty books" by-and-large. Maybe a few, but certainly not most of the time.
But my understanding was the conversation had moved on from that. I'm not talking about people being free with their sexuality; I'm talking about people not being allowed to be. People being pigeonholed in specific domestic roles. As Agema has pointed out, educational institutes have been found to be artificially depressing the grades of female students, which is an effort to force people into specific roles. The overwhelming pressure placed by parents is another form of social coercion.
This isn't perfectly free choice I'm talking about, here, and it's the opposite of sexual liberation. If you want people to feel sexually liberated, then this is the kind of stifling influence you should be standing against.
If we are to be truly socially liberated, we need to be able to see the nuance between someone enjoying something and someone thinking it's a moral good. We can do this with fast food, we know it's bad for us but we still enjoy it and we understand that we are capable of holding both thoughts in our head at the same time, but oh if you enjoy this sort of anime or videogame you must also think that the only thing women are good for is being broodmares or whatever hyperbolic term was being thrown around willy nilly here. It betrays that all this talk of liberation is hollow. You're only liberated to do these specific pre-approved things that back in the day people weren't permitted to do but if you go outside of the new boundaries you're still chastised.
OK, I think there's an element of defensiveness here, probably because you're a big fan of anime & Japanese video games.
So am I. You can enjoy whatever content you want (within reason obviously); this is not about judging anyone for liking Japanese stuff. In every medium on the planet, some stuff is going to get created with some poor depictions or shoddy idealisations in it. If we're reasonable human beings, we can consume this stuff, but still recognise if/when it gets to the point of adversely affecting how people are treated in real life.
Look at 50 Shades. Real shitty depiction of the BDSM subculture in there; idealisation of abusive behaviour, etc. But I don't doubt most readers are able to consume it, and would still recognise and decry if abusive behaviours started to get idealised IRL. Ditto anime: have your fill, but be willing to recognise that if real women are getting restricted to certain domestic positions in life, then that's unhealthy. There's a difference between art and life.
