With the Galsei subtext approaching critical mass, is the Deltarune fandom ready to acknowledge that Kris probably wasn't "born non-binary"? I get it, I get the appeal of that fantasy, but Deltarune is a game with a lot to say about gender and Kris, as a non-binary teen in a pretty cisnormative place, is part of that.
Mancountry. The pizza deodorant. Watching your dad do bonding activities that are for "the pals" and "the boys" only. The way the weird route puts Kris into the role of Groom in an abusive partnership, bestowing a ring onto their childhood friend in a white dress.
It doesn't invalidate the character, or anyone else, to pick up that there are gendered expectations placed onto them - even if it's not explicitly said by another character, there's a spectre in the air around all of those things. And that spectre is coercive gendering!
(of course, there's plenty to be said about how people are averse to really acknowledging the existence of non-binary transfems, and how "humans are just born without gender" is kind of a copout from having a trans protagonist in a story that heavily touches on identity, gender and dreams)
