Yeah, it's best to just ignore what the toxic Twitter users have to say. They just stick to being angry at things (Like, it'd take a miracle for them to just let go of Fire Emblem already), shut down any candidates regardless of arguments (They don't care if your character is popular in Japan, has close ties to Nintendo or is from a game integral to the industry, etc., apparently) and just blatantly ignore anything that objectively shuts down their arguments (Spirits Deconfirm -> Min Min & Pyra/Mythra, No Western Third Parties -> Banjo & Steve, Only one non-Echo character per third party franchise -> Sephiroth).
Whatever sort of mental exercises they go through to not just throw in the towel at all is beyond my knowledge, but in a sense it's kind of impressive that they just don't break even after being proven wrong several times.
Anyways, just don't pay them any mind and leave them to be screaming into the abyss if Reimu does get confirmed.
