Apparently, people can't quite handle the fact that icky slavery is a thing in the setting or that a dark-skinned race participates in it. People also point out the unpleasantly porny nature of dark elves and while I can kind of agree with that in the main, they also seem to forget (or never knew to begin with) that in the primary (Forgotten Realms) lore that inspires the material, Lolth deliberately twisted and corrupted dark elf society. (Partly as a "take that" against the rest of the elven pantheon after being cast out--see what you made me do to these elves who chose me over you, this is your fault--partly because it leaves them more susceptible to being controlled by her directly, and partly because it makes them less likely to leave her influence due to being shunned by other races.)

I like PF, it's been a nice continuation of the rules that I'm most comfortable playing with, and 2e has so far been a decent enough successor. But I think it's also going to be my last run with Paizo. The company has gotten more and more invested in applying IdPol to their material, and while the drow specifically are due more to avoiding potential legal issues with WotC, the discussion around the matter highlights how people with a strong investment in editing, censoring, or outright removing anything that they deem "offensive" are becoming more and more success at twisting the game to suit their ideology. There are least some comments pointing out how ridiculous it is to pretend that things like slavery don't exist because a minute fraction of players (or a bunch more people who never played and never will) have a problem with it, or that having dark skin and being evil is not some sort of subtle dogwhistle against real-world races. But those comments are few and far between.
