Anything I could say has already been said but I'll just go ahead and add my cents. Lol. I feel like anyone should feel okay to play anything they want. When I was younger, I had a hetmale friend that actually liked shoujo romance manga more than I did at the time and there was nothing wrong with that! I grew up playing a lot of male oriented Visual novels (there wasn't really even much otome around then, especially not in EN)
It's always been weird to me how people apply gender level acceptance to certain things. Well, a lot of it is toxic masculinity related and how much rigid criteria people have for views on "being a man." As an autistic person, I definitely never understood those societal exclusions lol.
the only time such things would be a problem is when people try to go into fandoms without respecting common sense fandom values. You don't go into a genre fandom and ask them to change to cater to you. The world doesn't revolve around a specific individual. That's not a gender specific thing though, like it's been mentioned, toxic fujo bleeding over to otome etc. Those people are best ignored. If you don't like something, don't engage with it. People have really bad main character syndrome these days, I blame the rise of internet "likes" and wired brain changes from current day social media...
but anyway, people play things for all sorts of reasons. some self insert, some don't. there are all kinds and I would like for the world to become a place people can just feel comfortable enjoying the things that they want to enjoy.
