Denying other theories with the same logic as (some) Tralsei deniers
What I mean is basically considering only one or very few pieces of evidence for the theory with a very superficial view and without taking into account all the other things
"Oh so you think he's trans just because he likes the dress and other feminine things???" is a point I see SO OFTEN and I'm like "NO, IT'S NOT JUST BECAUSE OF THAT".
I don't even believe in some of these, but it's funny to see how easy it is to deny everything while focusing on just one detail and ignore all the rest which is often more relevant and important:
CH3 Kris slash: Oh so you think just because they have a sword they did the slash?
Onion was killed by Normal_NPC: You seriously think Normal_NPC killed Onionsan just because Onion doesn't appear in Ch4 and Normal_NPC is there???
Deltarune is connected to Undertale: Smh why do people say believe this just because Kris' name has almost the same letters as Frisk then this game is connected to Undertale???
Dess/Holiday family member is the Knight: Oh so you think that just because the Knight has antlers they must be Dess/a Holiday?
Noelle is/will become the Angel: Smh you think that just because Spamton called her "Angel" one time???
Kris has a crush on Susie: Bro just because they defended her against King in Ch1 it doesn't mean they like her that way.
