Mate isn't your comparison a bit too extreme. I mean the average villager didn't even know that the uchihas were being sidelined by the likes Tobirama and Danzo. Even during Tobirama's period, he gave them a respectable job. The situation started deteriorating after the kyubi attack after which a lot of higher ups began suspecting the the uchihas whereas a normal villager still respected the uchihas as a powerful noble clan. Its quite apparent in the aftermath of the uchiha massacre throughout the manga.The Uchiha Clan were oppressed and treated unfairly since Tobirama's induction into being Hokage. They were stripped of everything and got the crumbs while everyone got a slice of the pie. Without the Uchiha, there wouldn't be a Konoha. The Naruto world would still be torn by war with Death winning on every term.
The Uchiha were like how African Americans were back in the Civil Rights days a half a decade ago. Oppressed, beaten, killed, and spat at. If Hashirama would've put his foot down, none of that wouldn't had happened. But just like Hurizen was to Danzo, Hashi was way too soft to the point, he bowed his head to the other Kage at the Summit.
And Itachi wanted to keep it like that, so I don't know where you're getting your facts about the uchihas being treated badly like an african american during the civil war.
