ambris asked: So I'm curious as to why incest porn is a squick to you. I'm certainly not challenging, as I understand everyone's got their own fetishes--just curious as to your take on it, and why is seems like such a bad thing. Furthermore, I seem to recall you mentions that Celestia/Luna is the one exception to said squick--why is that?

My rules give some explanation. (Everyone reads my rules, right? XD Maybe I should link to them everytime I mark “RULES VIOLATION" or “RULES WARNING”.)

Anyway, my first encounter with incest in furry (not exactly pornographic) was in “Better Days,” a webcomic by furry artist Jay Naylor. The chapter I linked is where it happens (or is heavily implied, anyway). That was probably my main turn-off to incest in pornography.

More generally, sexual reproduction between closely-related individuals is disadvantageous in natural selection, because it does not create as much genetic diversity. So there is a biological reason for avoiding incest, which could lead (justifiably, in my opinion) to the cultural avoidance of it.

However, I think incest has more to do with the relationship between the individuals. Adoptive siblings are not closely related biologically, but I would still consider sex between them incest. Family relationships (I think) are asexual (going back to the biological advantage), and since the relationship between adoptive children and other members of a family is about the same, I would still consider it incest (and thus wrong to some degree).

Now the Celestia-Luna exception. You might be referring to this post, in which I mention the exception; I also mention it in my rules. In the rules, I point to a clopfic, "Tipsy” by Anonymous Pegasus on FIMFiction, whose handling of the incest desensitizes it a bit to the cultural taboo.

More generally, I make the exception because, frankly, Celestia and Luna have a pretty flimsy claim for being “sisters.” All we have for that is the first episode, but there’s no history of their birth, their parents, or their childhood. (I doubt that they’re even sisters in the traditional biological sense.) Like I said, I think incest is about the relationship, so the fact that there isn’t much of this relationship between Celestia and Luna makes it seem less like incest than if the “sister” claim is taken on its face.

You know, I read that comic myself some time ago, so I know exactly the scene you’re talking about. I honestly don’t have a clue why that inherently makes it a turn-off.

For the record, I definitely don’t approve of long-term incestuous “relationships”, because things get entirely too complex on an emotional level. And I’ve always felt that efforts should be made that inbreeding never happens, for obvious reasons.

Personally, I find that reasoning for Celestia and Luna incest to be… odd. Flimsy logic even. But I guess if it works for you, more power to you.

I guess I struggle to understand why people are against incest porn.

To me, it’s simply a matter of having a good time with people you trust; as all sexual encounters should be. Why is that so bad?

“Flimsy logic”? Come on!
Jean-Luc Picard: "Oh come on, how can he not see that! Really!"

I’ll admit that that was my initial reaction, but now I’ll respectfully disagree. Maybe I should elaborate by starting with the clopfic I referenced:

Luna lifted a socked hoof to touch at her own chest, turning to face Twilight properly. “Thou understands [sic] that our sister and we are many, many years old?”

Twilight nodded at that, tilting her head to the side slightly. “I know that it’s over two thousand years old.”

“Then thou knows [sic] that we do not have…parents, as it were?” Luna continued, raising a brow.

The young unicorn frowned at that, and then nodded again. “Indeed.”

“Our sister and we are close. We are closer than family. We are like the sun and the moon itself. We sisters, but we are alien to each other. There is no family between us except that which we choose to acknowledge,” Luna explained, giving Twilight a warm smile. “We are sisters…but we are not.”

Works for me!

I see a lot of fan work that depicts Celestia and Luna as fillies, but none of that is canonical. This is opposed to the other family relations depicted on the show (the Apple family, and Twilight Sparkle and Shining Armor), which actually have canonical childhood histories and parents. We don’t even know who Celestia and Luna’s parents are, or even if they have parents.

This ambiguous childhood relationship also explains why I’m okay with Celestia x Cadenza, even though according to the “wedding announcement” in the New York Times they’re aunt and niece; Celestia and Cadenza also don’t have much (if any) canonical family history.
