Ok, just a reminder that Kris, Frisk and Chara canonically go by they/them pronouns(they/it for Chara) and it should be respected as such regardless if it's AU stuff, if you still insist on using different pronouns compared to canon, try making a new human OC for your UT/DR AU(plenty of people did that).
Also, if your assumption towards someone simply correcting you on something(and they're super polite about it and giving gentle advice) is that they're not old enough to be on the Internet or whatever, then clearly you're kind of the asshole here.
It's not that hard to respect a character's or anyone's pronouns.
Also before you get mad at me and call me a hypocrite, while I headcanon certain characters to go by certain things, at least I try to respect the stuff that's already canon(for example, D1AL from The Walten Files is canonically nonbinary and goes by they/them and I remember this, so I leave it unchanged while I make other headcanons), it's that fucking easy.
(Totally not based on an interaction I just had a minute ago or anything...)
