You know, I'm a person who thinks games are art. I really do! Code is as good as if not better than paper, a stage or marble. But people like you really don't make my job easier.
You don't write a story about struggle of any kind without any characters (unless you count the amorphous blob of caricatures who all share the single personality trait of "did a mildly rude thing once probably")
You don't help anyone get what trans people are going through by publishing horribly-made games because guess what? Empathy exists! "I hope that it can give cisgender people an idea of what being transgender is like"
Not an in depth look, not an explanation, just "an idea" because no outsider can even comprehend your struggles.
And please for the love of whatever god you believe or don't believe in don't put glitchy sand-crushing noises in anything. It doesn't set any mood, it just makes everyone mute the game. What did you think would happen?
I don't really see myself as a sexist person, you may think otherwise which would be wrong by your way of thinking. Way to assume that everyone single "person who writes comments under games that are milking the emotions of people struggling with serious stuff" is sexist!
You can judge people by appearance, it's easier. Way easier. You do it, I do it, everyone does it! You are in no way obligated to spend the extra mental energy (no matter how miniscule it might be) to think about pronouns and shit. When talking to strangers that is. With friends or people you know, you absolutely should refer to them the way they prefer. Even if it's something as small as using a second-name or a nickname.
But still, no stranger has to give a single time-bending shit about you. Especially if you're always bitter about people not magically being %100 conscious about making you feel comfortable all the time.
Just get you head out of your fucking ass, and explain it to people if they ask. If they don't just ignore them. You don't become morally superior by over-explaining other thing so why would this topic lead to anything else?
