That's definitely a change that has come over D&D and its offshoots in later years. The main thing that comes to mind is the very first AP part from Pathfinder, Burnt Offerings. As the adventure starts, the PCs for one reason or another are in the frontier town of Sandpoint to witness/take part in the dedication of a temple dedicated to a handful of different deities, when the town is attacked by immensely savage and nasty goblins. They're terribly disorganized, setting fire to things randomly, going after the weakest people in town (like children). As the adventure goes on, you learn that they probably have the support of at least some people in town, because otherwise they wouldn't dare do things like that, and IIRC something about different goblin tribes not being able to work together without outside leadership.
I'm sure that wasn't James Jacobs' intention, but the whole thing felt a lot like a western of the old racist kind, where the part of the Indians was played by the goblins instead.
