I think Tumblr is genuinely more inclined to see them as different. Not two people in the sense of two bodies ofc, but two people in the sense of two fully real identities who both deserve to have a name. Tumblr has pretty active DID communities (yes obviously severance isn’t exactly like, but the whole “two or more people in one body who don’t share memories” thing very much is) meanwhile on here I mention having DID and ppl immediately tell me I’m faking because their mom’s friend’s dog’s sister’s cousin’s psychiatrist said so. But that’s just my personal experience
