Its more that people are scared they would be accused of misrepresentation. There can be two types of writing styles, one where the mindscape of MC is not touched deep and another is where MC's feelings are touched upon often. Authors need to find the sweet spot to make the MC relatable to both male and female audience. And authors do this by centering the story around MC. Fallen Hero, Golden Rose, ITFO comprise of the latter and the sandboxy IF's comprise of the former. Both have its challenges, wordcount, branching, plotline, storytelling all is affected by the style of writing.Meanwhile it's like... feelings are feelings. I could write from the PoV of a man, a woman, a dragon, or a sentient toaster, and I don't feel it would've made much difference. Feelings are universal for everyone sentient.
People sometimes overcomplicate things.
Fallen Hero does the best in this regards imo. There is branching, the writing style is fairly descritive although sometimes you cant understand **** during dream sequences. I had a thought that maybe the story was written around the concept of representation rather than writing a story for the sake of a story. The MC happens to be traumatized and is not comfortable in their body due to their origins, has a second body they can jump to and be 'comfortable', body swap into that body permemntantly based on your comfort in that body. Half the story is about this. Yet this is sympathisable regardless of your gender. Cis people would find it uncomfortable swapping into puppet and see it only as a tool and vice versa for trans people. Tbh this is one of the biggest reasons why people love FH considering how much of IF community values representation and inclusion which is not a bad thing unless the rest of IF takes a hit for it.
So what im trying to say is, if you are confident you can manage representation, inclusivity etc without affecting the other parts of the IF then fine, if not then thats fine too. No need to bully one or the other side.
