No, it's more like I want D&D games to be plausible.
It's not plausible when monsters roam city streets as if they are normal civilians. As a player, I don't want to play D&D campaign like Star Wars where there is a plethora of hundreds of different races of humanoid aliens in the majority of cities, most of whom get along for the most part shy of the worst parts of the cities.
Instead, I prefer a D&D where most "monsters" are evil and where there are few social consequences for taking them out. Monsters should be outlaws and races that are not monstrous should be known acceptable members of a given fantasy campaign setting. There should be a reason in D&D campaigns that monsters are called monsters.
And successful monster knowledge checks should let players know of creatures that are "not generally considered evil or monstrous".
Granted, every campaign will be different, but I prefer logical settings to illogical ones. For example, even in the city of Sigil, monsters walk the street and do not molest each only because of a logical reason. The Lady of Pain will throw them in a maze if they do not. They are forced to behave. Monsters in more traditional non-Sigil like areas (like the majority of areas in many campaign settings) should typically have other racial enemies (including PC races) and should typically be malevolent, not benevolent. They shouldn't be forced to behave and laws shouldn't protect them.
Note: I have no problem with monsters being in cities if they are hidden or disguised, I just have a problem with the concept of live and let live; Trolls and Humans working side by side in a city. That to me is not D&D. It's Star Wars. It's the wrong genre.
Eberron introduced a lot of this with "laws of Sharn that protect all humanoid races" and it's just lame. IMO. Meh. Sharn is too 20th century sensibilities for my tastes. As for my posts in this thread, this thread is about races that people hate. I hate monstrous PC races.
