I like the world of Golarion, and appreciate the effort to make most people likable (i guess that's next to impossible for diabolists), but some seem to get the bad end of their stereotype only. (based on what i read in the Gazeteer)
Taldor is decadent and paranoid only. Doesn't seem to dwell a single decent man or woman there.
Belkan. It's Orcs. And gamers need something they can "love to hate"? Even the paladin needs people he can gleefully slaughter and be called "noble" for it. 'nuff said.
Mwangi. Primitive, jungle dwelling primitives, that resisted hundreds (!) of years to civilize them just to turn feral again the very moment the structure of their benevolent "massas" fails. On top of that, lacking an own God, the fall in droves to evil superstitons to follow and undead mummy master.
Now, I am aware that the PFC Gazeteer contains several critical stabs at religious zealotry and imperialism, but in the case of the Mwangi the colonial narrative reamins intact.
These are minor points, and I agree that the equality between genders is handled failry well, but there are still hierarchies of civilized / primitive and good / evil based on race. In a large part, this is due to the inclusion of metaphysical evil, but that would be another topic.
