This goes with the "Some are dicks, some aren't" version quite nicely. Group A wants to just do their thing and not have other races suffer/get involved in any capacity besides maybe trade.
Group B is a bunch of high and mighty pricks who view everyone else as less than their own race and are willing to cut them down for the slightest thing/to get at things that they might want or need, while veiwing Group A as a bunch of bleeding hearts that care a little too much about the savages and have no stomach for a fight when one is deemed needed. Group B is also probably the vengeful sorts of the populous.
Group C is the "leave us out of your arguments" silent/not really vocal majority, simply trying to go about their day. If they feel fighting the various critters such as dwarves or humans will be worth it (say to get a few metric fucktons of raw materials they need for their tools and such,) then they'll fight but otherwise like Group A would much prefer keeping to themselves, and interaction with other races to a minimum.
Group A and B are essentially the extremes, with A being our equivalent to animal rights people (that paints them as dicks still don't it?
) and B being full blown "FUCK EVERYTHING" and willing to kick the utter shit out of anything and everything for whatever reason (revenge for some of their fellows, resources, or if the Seqivet don't frown upon slavery, even beating down and subjugating them; after all, they don't seem like the types to work underground for long periods of time.) This group may also count generally belligerent jerks looking to cause trouble for the sake of causing trouble, much like manamaids who go out looking for fights because they find it fun.
I dunno. I just woke up so some of that may lose cohesion or sound repetitive.
