I know that they aren't exactly the prettiest races to look at, but they are very cool to play as. It seems modders would rather spend their time making slu tty babe improvement mods and skimpy armour for human characters, which I think is dissapointing since a lot of people, myself included, play as Khajiit and Argonian.
EDIT: When I mean 'hate', I mean there isn't anything there for beast races. The cool stuff like Contracter or Seratic armor, or even Dragon Priest Masks in the base game completely cut off the snouts and mouths of beast races or are completely imcompatiable simply because of the skeleton shape. If it's not compatiable, find a way around it and make it so!
