Agreed. For whatever reason, anything remotely resembling "teh furry" seems to uniquely upset some people.So many people complaining about the Zoologist just because she's an antropomorphised animal... I mean, we already have a literally half-nude nature spirit (Dryad), a humanoid lizard witch doctor, a humanoid fungus and even a cyborg... She doesn't feel so out of the ordinary for Terraria.
But looking at the bright side, one great thing about Terraria is the ability to easily use texture packs (especially now that they'll be more accessible than ever in 1.4). I'm sure they'll be one or two packs that will make this npc look more basic or whatever people prefer, so everybody wins!
