The rain world fandom has a racism problem (Scavengers and Artificer), a fatphobia problem (Gourmand) and a misogyny problem (Monk, Artificer and Gourmand).
I would also like to say that despite being the only slugcat with actual pronouns used IN GAME I have never heard a person in this fandom call Spearmaster by they/it.
Moon is also a victim of misogyny and Pebbles and sometimes the vanilla siblings suffer from being infantilized, and the characterization of Rivulet as Moon's hyperactive child can easily come off against ableism againt people with ADHD, and who knows what else I'm forgetting... man. These issues deserve to be discussed more than they are, which is almost zero.
I know the fandom doesn't do it on purpose, okay? I know. But please, next time that you want to make up your big lore post on all the ways scavenger society is terrible and oppreses slugcats or your comic where Moon's only role is to be a nice loving big sister to her angsty little brother Pebbles... consider why you're doing that in the first place, why do you think it should be like this. Please and thank you.
Oh and on the topic of slugcat gender, Spearmaster's one of two that have pronouns:
"Ah, you remind me of a old creature who used to visit here often. The passage of time has taken them away, of course. That was a while ago." - Moon in Saint's campaign, third encounter.
If you wish to cite the Dev Commentary as those who push that Artificer is canonically female do then Gourmand and Rivulet are canonically they/them:
sh_gor01-white (Defining Gourmand and Community Theories)
Will: We had a lot of difficulty early on deciding exactly what Gourmand was going to be about, or if they even had a place in the story.
Will: In a way we did both of those things, by putting Gourmand's existence intentionally in question. They are such a bizarre creature!
Will: Spearmaster, Rivulet, and even Artificer to some degree have some in-game explanation now.
Will: However Gourmand's powers seemed too extreme... how could they have such an endless supply of things?
ds_rivstart-white (Life of Rivulet)
Andrew: Rivulet starts out with The Mark, but I don't view them as necessarilly having been raised or trained
as a messenger by an iterator similarly to Hunter or Spearmaster. They've made contact with one for sure, though.
Andrew: Rivulet is an adventurous, curious, and agile slugcat that travels long distances across the land,
and I imagine they've gotten into all sorts of wacky adventures even prior to the start of their campaign.
Isn't it funny how she/her for Artificer is the only part taken as irrefutable proof and the rest is ignored? I find it hilarious!
