Weird how when every Naruto character talks about the Uchiha clan, they have either zero reason or zero authority to be a reliable narrator. This isn't unique to the Uchiha, but given all the fandom and in-universe discourse about them, it stands out.
Where's the Uchiha counterpoint to Tobirama's dumbass mood disorder theory? Oh right. Konoha got rid of them and now they can slander them without anyone to call them on it. Tobirama is so ridiculously biased that even Hashirama scolds him, so I'm not trusting a single word from his mouth, but Hashirama doesn't have any claims to being a better authority on the Uchiha.
Madara should know the most through virtue of actually living to adulthood in the clan, even if a couple generations ago, but Madara is fully despairpilled and therefore unreliable by the time we meet him.
Obito and Itachi are both brainwashed by the elders in their lives and also not reliable judges of, uh, anything. They also left the clan as children. Itachi is under a pro Konoha genjutsu when he shows Sasuke his memories, so who even knows if those were altered.
Hiruzen and Danzo are obviously negatively biased to a genocidal extreme.
Hagoromo? A big question mark as to how his motivations fuel the information he relays, plus he's a thousand years out of date.
So we will never actually know what was going on with the adults in the clan, or what their cultural characteristics were, or almost anything at all about them prior to the massacre—it's actually a huge hole in the narrative that feeds both Sasuke's sense of loss and his later existential spiraling. He lost his whole culture but before he was old enough to have the knowledge to recreate it. Then, it's unreliable narrators all around him when one of his defining characteristics is wanting to know the truth.
In the end, however, both Sasuke and the audience should be questioning more often what they know vs what they've been told about the Uchiha, and especially whether the people doing the telling have any leg to stand on.
