There is nothing deep about all Mongolians being murdering savages or all orcs being stupid barbarians.
Not
stupid barbarians. But barbarians, nonetheless. You forget that a race of barbarians can have depth to it. If you stop and look, a lot of barbaric races through history and media have been misunderstood honourable people. Even in TES, pre-Morrowind.
The same can actually be said about the Vikings. Famous for being savage themselves. But, when you stop and look, Vikings have a rich cultural background. Thier gods, sense of honour, hospitality to thier own, etc. You seem to be the one stereotyping, imo.
And I said nothing about
all Orcs being barbarians. There should be exceptions, but, on the most part, they should follow thier racial traits. Think about Native Americans when America was first being colonized. To those setting up shop, they appeared to be a bunch of murderous savages, but when you get to know them, thier history and background can be an interesting, in depth story.
Imo, the real problem with Orcs, like most races, are the voices. Oblivion's voices are awful. They don't sound anything like a savage race. They may not actually
be savage, but they seem it. The voices don't sound like they should. They sound happy and forgiving. The reason there's been such hatred to the Orcs is because of how they seem to be savages. They don't anymore.
