I don't know the specifics of the timing for what is a mother in the DV, that is a question for JB. I'm just arguing that it raidem's argument is internally inconsistent because it is twisting a definition to suit a particular purpose, rather than picking a definition and then applying it logically in all situations.
And, I'm arguing it is internally consistent as I just outlined previously based on the words definitions.
mother is defined as having given birth
mortal is subject to death.
human being applies both to the unborn fetus and born fetus.
If the Queen can't kill human being, then she can't kill the unborn fetus. This isn't yet a condition of 'mother' which I'm arguing from.
Toward your point there are two rules in play not just one to which you allude to which is why my argument remains consistent. The 'mother' rule is distinct from the Queen can't kill 'mortal' rule. They have different definitions but have some overlap but not in the case in which is being argued: that of the unborn fetus.
I'm just pointing at that you can't have it both ways. If raidem wants to argue that the Lady can get pregnant but can't give birth, it is inconsistent to argue the mantle couldn't force a miscarriage to prevent birth.
Oh, I see where you may be arguing from.
Let me be clear on one point that may explain my approach. I do argue "that the Lady can get pregnant but can't give birth." I also realize the Lady has a defense mechanism to prevent sex, which then prevents conception, which prevents birth. I view the defense mechanism against sex as the wall of a castle, once you are able somehow to get past it you're potentially inside the mantles defenses whereby conception is possible. Should conception occur, you are now pregnant. By virtue of rules regarding the Queens killing mortal humans, the Lady mantle may make no attempt at this point to kill the fetus. Its primary defense mechanism, the wall, is irrelevant and now the mantle is in overdrive to push the Lady to become the Queen. This drive then becomes the second line of defense, the Lady will succeed in becoming Queen prior to giving birth therefore it is a nonissue for the Lady mantle or the Lady dies in the attempt, the Lady mantle passes, therefore it again is a nonissue for the lady mantle. Only when the Lady mantle is trapped when the Lady gives birth is the Lady mantle destroyed in the process.
So, given my argument above, I have shown a internally consistent way in which the mantle lives with the condition of pregnancy and the drive to protect itself. I believe you assumed that I asserted no further self-defense mechanism past the no-sex mechanism. I didn't. Again, the self-defense mechanism then becomes unseat the Queen at all costs prior to birth. This could then allow an additional pressure taking place within faerie back in the time when both Queens died 1000+ years ago. The ladies were also on a timetable.
Murphy was on a timetable. (It's a fiction I'm creating in my head, and I like it.)
