Maybe you should not post if it annoys you so much when people talk about such issues. Class oppression is a common trope in human history and its art, so it does make sense to include it in one way or another as it a) creates interesting stories of heroes overcoming such struggles and b) it can make a deep simulation like dwarf fortress rounder and more realistic.
In my opinion there should be worlds where this is a part of the history while still having worlds where there is no class struggles, though I find that quite silly as about every civilization has had these struggles one way or another. These struggles continue to this day in some countries so I wonder why it poses such a problem to you when people discuss these possibilities for the game.
Furthermore I would like to point out that your first sentence as well as your pc assumption read as passive aggressive, but as I believe that your ibtention was not to infuriate, I wonder if you could use a less aggressive language to get your point across.
And now I feel myself a little autistic because I were not able to tell right-away if this post was meant as a a clever irony or not.
To answer your question. My criticism was not meant to be argument-filled complex discussion about society and classes, because I find these discussions generally not guiding game development at all. DF developers take general ideas and try to put them inside the framework of the game while not trying to follow every single philosophical implication that it brings along.
My criticism was only meant as a metaphorical *smack* to GoblinCookie's head, because I don't find the guy dumb and I wouldn't even care if GC was dumb. But the problem is that he is very obsessive about certain ideas. And I actually find it kinda fascinating how this obsession leads him to react to things and ideas very specific way. Like in the topic of "Dwarven Social Lives" he brought out some existential ideas he found horrifying and I compared his existential fears to mine concluding that he is probably metaphysical opposite of me
since, I am also obsessed with different philosophical ideas and ideals, but they are located in opposite spectrum.
I have realised that these obsessions are unhealthy when not controlled. And in case of myself, when I find out that I act on behalf of obsession, I metaphorically smack myself and ask - "Is this me or is this my obsession acting out right-now?" This simple Cognitive-behavioral technique has helped me to find out if my behaviour is unconstructive and save huge amount of my time and energy. Otherwise I fear I might be really annoying person in every social circle
I hope this explained my post and my emotionally motivated need to smack GC while telepathically yelling him that "Hey, you don't have to take these things obnoxiously seriously!"
