Because, you know, the only way to have politically correct diversity is to treat people like objects and count them up.
Does this guy just go around looking for trouble where there is none?
Most of the Kurach females you see in dresses and the males you see in pants dress that way because it is the most convenient way for them to pee. The females just pull their skirts up a bit or spread their legs and the males just pull their pants down a bit. Plain and simple. And before you ask, no, some guys do not see it as convenient for them as the ladies to wear a skirt, because unlike females, they are better able to aim themselves out of the splash radius without fighting a skirt the whole time and they intend to take advantage of that.
Not to mention pants are less likely to get caught in the bushes on a hunting trip.
As for the "traditional roles" thing, you must be referring to Wynfall, where the humans have achieved enough wealth where only one of a mated pair has to obtain necessities and the other can keep the nest tidy. All the others you've seen — Kurach, minocentaur, goblin, gnome, whatever — typically need everybody working to obtain necessities and assign people as they're most helpful. My great-great-grandma was a great hunter, so her mate repaired and mended. I was not considered a good hunter, so Katari and Hilael got to have all the fun while I was stuck darning darn socks. We react, we don't assign.
As for us humans, it's roots are traced strongly to horse riding! Everybody started out in skirts. Weaving a rectangle and fastening it to the waist is about as basic as you can get. But once horses started to become tamed, it was time to find something to protect the inner leg, as any seasoned rider is quick to tell you. Since the ladies were often left at home with children as their bodies were better accustomed to rearing the very young and the gentlemen took it upon themselves to pick up the slack in larger scale defenses, it eventually fell to wear trousers were a symbol of masculinity and skirts a symbol of femininity.
Along those lines, skirts and robes became a symbol of nurturing and peace, which is why you find so many of the priests and us scholars wearing them. Battle is not our duty.
But that's in the warmer climates. The further away you go toward the cold, the more likely you are to find everybody donning trousers. As many of the ladies can attest, skirts can be very cold to wear.
Oh, look, one from the other side! If you like dresses that much, you can go wear them. Not that many people realize it, but, raising kids is more about maturity and responsiblity than it is whether your pair is slung below your legs or strung between your shoulders.
Junaid is an ambassador from the hottest country, and thus has the darkest skin of any met so far. Aside from weirdos like me, ambassadors are the only long-distance explorers. Scouts are short-distance explorers and will at most accompany an ambassador to protect him. Ambassadors have to make sure an area is safe to trade with or for the more vulnerable of his people to travel to in larger numbers. Our world is in a state where most are focusing on survival and not so much on exploration or settling in a new territory. Even the nomads. If you'll notice, most other peoples have stayed in their territory that weren't trading or conducting negotiations.
If I ever take a proper trip to Bhadarukia, you'll get to see plenty of "black guys".
*smacks head* Oh good grief. We Kurach are not "white". If we were humans from earth, the Prairie Kurach would be varying tribes of Native American and their desert cousins would be Arabic, the Island Kurach would be a Samoan, Maori, and Greek mix, the Highland Kurach would be a Saxon and Norse mix, the Arctic Kurach would be an Inuit and east Asian mix, and we Sylvans are some combination of Celt and Indian. India Indian, not Native American.
At present, the Islanders are our darkest kind because they've been in the sun the longest, but eventually the Prairie Kurach out in Bhadarukia will darken over time even more than the Islanders. It's a natural evolutionary kind of thing where the body reacts to its environment. Do you not read the history and science books of your world to know how adaptations work?
The powerful, hefty Highland Kurach are kin to the tundra wolf, a subspecies of the grey, and like their smaller cousins hunt large game to survive.
The Sylvans are kin to the grey wolf, and while the grey is larger than the tundra, the Sylvans are smaller instead of larger than the Highland due to the bird they owe their wings to, and also why they have a more varied and omnivorous diet than the highly carnivorous Highland.
The Prairie and Desert Kurach are the coyotes and jackals, respectively, of their families. Like their cousins, they do not need mainly large game to survive and can afford a smaller body style. Given the warmer climents they prefer, their ears are larger than the other breeds to help them keep cool.
The Islanders are most kin to the Falkland wolf, who is in turn most related to the maned wolf. While they also live in a hot climate, they spend much of their time in the water, and therefore have developed smaller ears and other features more suited for swimming.
Then there are the little Arctic. As is likely obvious, they are kin to the arctic wolves. Or maybe the foxes? They're all so stubby and fluffy, they all look the same to me up there!
