Let me stress again that I do consider it an interesting addition that makes sense for the game and would be an enrichment. It is just that I feel the damage that will be done in its environment outweighs the benefit in that case.
Deathworks
The thing is this can happen with tons and tons of stuff, vomit, sex if its added, it already kinda happens with violence, hell as far as we know it could happen with racism now that we actually have the chance.
I think its the fact that we are used to the whole killing elves and burning people with magma that makes us not notice, but its in fact quite dark, i remember finding the whole idea of killing my own dwarves kinda dark at the start. Sure there will be some jokes about it, but i really doubt we need to avoid what can be a REALLY important subject wen it comes to urban design, just because of the risks that we are taking with almost anything else, that we only allow because that we are already used to violence in the game.
I also think that those posts with jokes about feces are kinda like the face palm joke one, since they are not common wen you get one, they grow more than usual, in the regular use of jokes about that i think it will get fixed on its own, mostly because of the rejection they will get from other users, while most of us can make a shit joke every once in a while, you rarely find someone that makes them ALL the time, for one simple reason, its not funny, and since its not funny, while some of us might like to torture some elves by droping them on a pit of feces, i doubt we will use it as magma because the rest of the members will hate us for doing that.
That said i think there are many ways of introducing the general concept without needing to ever mention feces, you simply make a building called "bath" with access to water in wich the dwarves take a bath and you get some sort of dirty or contaminated water, those that like the idea of feces can think of it as the dwarves using the bath for both feces and washing while those that dont like it have nothing bothering them, since its them just washing, and it should please all of us that would like to build a sewage system and take care of that sort of problem.
