There are good and bad Uchiha. They tend to take everything to an extreme, so of course when they turn bad everything tends to get really messed up and people remember it for a long time. Tobirama was kind of right in that being an Uchiha basically makes you a ticking time bomb. I think his solution of keeping them as Konoha's police force and giving them their own section of the village (which as far as we know, not even the Hyuga clan had) was a sensible and compromising option that would keep those bombs from igniting. People say it was harsh of him to "sequester" the Uchiha like he did, but it really wasn't - he was being pretty generous and helping everyone involved, and he actually gave them more than he took away. Fugaku's coup was a terrible idea that makes the Uchiha look really bad, IMO.
Itachi, Shisui, and Kagami are the "good" Uchiha we see, and they take ideals like peace and love for their comrades to the same extreme that the others take things like revenge and freedom. Madara and Obito are really extreme examples and probably would have been great people during peacetime. Honestly, the only Uchiha who I could say really get on my nerves are Izuna and Fugaku. In what little we see of Izuna he's pretty prejudiced against the Senju, and Fugaku has an alright personality, but basically dug the Uchiha's grave with his poor decisions.
