Whilst it's an interesting point of view, over-analysis is not always a good thing, the Dwarfs were, for example, driven out of Moria by both the Goblins and the remnants of Melkors army, including a Balrog, and Moria was created by the dwarves, at least until they hit the caverns underneath, before the Dwarves created it, there was no such place as Moria, secondly, the Goblinoids were a semi-animalistic race, distantly related to Melkors' Orcs, who were wholly dedicated to Murder and Bloodshed, I can't comment on the batwomen, since they are new to me.

I think it's easy to find comparisons in just about anything if you look hard enough, but the histories between the races don't really match to any extreme, it's a little too definitive of 'good guys' and 'bad guys'.

I look forward to reading this properly, but ultimately it's human nature (replace human with whichever fantasy race you like). It's the 'circle of blood'.

Warhammer fantasy battles goes all out with absolute racism on all sides, 'greenskins' are always to be killed and such.

Incidentally, I've been commentating on the original storyline script of StarCraft and one revelation I came across is that the situation is almost similar to North America with its colonisation and native inhabitants. Naturally, I mentioned that it's complete speculation and probably not even intended, as overanalysing is easy to do.
