Thank you junedave and lyrichartwell for your comments.

I said "where the only difference between male and female is at most pronouns." because the little we do see is of the trolls, humans, sprites and chess people on Earth C seemed to have created a culture where all of them live in a combination all all those cultures. I'm getting that from the shops, streets and the school we see with how their journey in Homestuck is treated as history you learn in school. This along with other things made me wonder what would people on this Earth consider feminine and masculine when they have both human and troll culture/media? Would feminine and masculine be that different to them and in what ways?

I also believe there is a lot of mischaracterization in the epilogues and HS^2 because I refuse to believe the characters in Homestuck would isolate themselves from the friends they knew/lived with for years. The only thing I've seen people say to support this is that they grew up but that is not enough for me. I do not believe that a grow of friends you knew for most of your life, that you fought gods with, that you create a universe with would drift away like they did in the epilogues.
