I was mostly just joking. But "red orcs"? Uh, you do realize Warlock is an orc (or Oglodi in Valve's made up world) and he's not red. Or do you only consider red Oglodi to be the superior type? Racism in Dota goes farther than I expected.
Actually it doesn't depend since there's no one with Thai/Pakistani/Indian etc. features.
I'm sure Valve will flesh out the "lore" of Dota and explain the races/tribes/etc., but some characters are obviously from the same "race" while others seem to be in between or their own thing. It's kind of a strange hodgepodge right now.
