@ David Bowers comment: Yeah, but even the humans didn't trust that the orcs 'had been beaten down'. They were too suspicious of them. But they were pretty much right anyways. Some defend the "new horde" as if its something different. Sure there isn't the demonic blood thirst, but there might as well be. Take a look at any of the other things blizzard is producing that show's orc society and its pretty much the same thing without the rampaging across continents (with the exception of BGs). Even the slight changes they have are usually placed squarely on the shoulders of Thrall, who, if were ever killed would probably sink the Horde back into it's old ways. Perhaps the Trolls and Tauren may help bring them back into their old Shamanistic ways, or maybe even the blood elves' influence with something new, but for the time being there really isn't much difference between the old and new horde.

ps. oh, and who's going to tell them differenty? The king of Stormwind, thats who. But I doubt he'd share your sentiment.
