To smeeprocket, and other rape/slavery exceptionalists:
Dwarves are not moral! Have you seen the things they do? Deliberately exposing their own troops to forgotten beast poison to make painless, fireproof soldiers sounds straight out of Unit 731, and that is just the start of it. Torture of various forms is in the game, with goblins pitted and slowly beaten or shot to death by recruits with training weapons. Rape? Yes, they do that too. Ask Obok Meatgod (though I do concede that that involved some modding and had nothing to do with Toady).
"People don't usually have magma-related accidents?" Tell that to the people who lived near Nevado del Ruiz in 1985. Most of them, over 25,000, died in horrific mudslides caused by the volcano. Would you remove magma from the game because of this? I can understand why you would want to if you had seen your family engulfed in volcanic mud. I would also doubt that you would continue to see it as just "over the top violence", either.
But you also have the option of not playing the game.
Dwarf Fortress is, if you have not noticed, mostly a gallery of macabre horrors. This has been evident ever since Boatmurdered. And, sure enough, many of the things that happen have happened to real people. If you had seen your family crushed by elephants - and some people have - then Boatmurdered would not be nearly as entertaining. So don't read it. I doubt many people who are sensitive to violence would play Dwarf Fortress given the stories of blood-drenched mutilation and magma that surround it. Why should Toady censor his game just in case somebody gets offended? He is not trying to trigger anyone, just to make his game.
"You don't play humans"? Have you ever played adventure mode? You can turn into a werebeast or a necromancer, for Armok's sake. Does not commanding an army of the dead count as a form of slavery? Besides, real slaves in ancient times were often treated far better than dwarves are treated now. It was undoubtedly better to be a slave in a rich Roman's house than to be locked in a tiny cell and left to die of thirst.
Though I disagree with your other points, I respect them. What I do not respect is turning your sex into a point of argument. None of us in favour of more horror in DF have ever expressed any intention to repel women to my knowledge. It is true that rape is not dealt with properly in the USA, but guess what - it's not dealt with properly when men get raped, either. Check out this website if you want to see:
http://spr.igc.org/en/survivorstories/main.html But I do not think - and correct me if I am wrong - that you have ever mentioned this in your diatribes as to why fictional characters should not rape unless it is a "plot" and is only "implied" (how on earth does that make it any better for the victim?) People having their heads sliced off is a very real issue too - look at Mexico and Iraq/Syria for the most obvious examples. What if - just what if - female DF players could actually distinguish between some ASCII characters on a screen and reality, and did not give up?
You are not a slave, as far as I know, anyway. You have the right to leave if you do not like the way DF is going. You also have the right to express your opinions. What you do not have is the right to make Toady, or anyone else, listen to them.
