...wait, so you just admitted that your analogy was NOT analogous? You realize that that's like, the point of an analogy, right? To be analogous? My god, is anyone else reading this?
It matters quite a bit, actually. If incest were a genuine, immutable urge like homosexuality, then we'd be having a different conversation. As it stands, it isn't. It's just a niche-fantasy under a much broader sexual orientation. No, it doesn't have to be heterosexual. But the fact that it's literally narrowed down to immediate family members, does not give it the same kind of weight that homosexuality has. You can invert the order of the arguments if it makes more sense. Because incest creates a source of fission in the family where none exists and homosexuality eliminates a source of fission (I'll elaborate on this below), and whereas homosexuality is immutable and incest is merely a repressable preference, we have more grounds to ban incest.
Alright, I'll spell it out. Here's why you made my argument for me:
The only way homosexual relationships are "destructive" under your scenario is in a universe where the option for gay marriage and a homo-normative relationship doesn't exist -- basically, the current world, in most places. The "coming out of the closet" argument don't matter if gay people have the option of entering gay relationships in the first place. None of that drama ever happens. So if gay relationships are allowed, the fission you're talking about disappears. All of the hierarchical family roles are the same, even if the gender within them is different.
With incest, It's exactly the opposite. If incest is allowed, the actual ROLES of the family become blurred, as opposed to merely the genders. Fathers and mothers now double as lovers. Brother and sister can be married couples living under the same roof as their parents.
So in retard terms...allowing monogamous homosexual relationships vis-a-vis marriage ELIMINATES the source of fission you're talking about....whereas allowing incest CREATES a source of fission where none exists.
I suppose now you could try and make the argument that a person who wants incest will show their true colors in any given marital situation anyway. But aha! Incest is NOT an orientation because, again, incest is not an orientation. If incest is banned societally, a hetero incest perpetrator can just go, "Oh well!" and have sex with anyone else. Just because he PREFERS a direct relative, doesn't mean his orientation doesn't allow for other partners. He has a release, so it's not immutable like homosexuality. Not so for a blanket homosexuality ban. There is no release because the restriction is much more fundamental.
Get it now?
Probably not.
If I may paraphrase your earlier point --- YOUR ANALOGY IS NOT ANALOGOUS.
I've already made the point that allowing gay marriage eliminates a source of fission whereas allowing incest creates one from thin air...so the idea of me having to ban gay marriage because I'm pro banning incest is already bunk.
Let's follow the alcohol analogy. "JJ, because you support banning incest due to its adverse affects on the family, you must also support banning alcohol. And hey, by the way JJ, you know what else can ruin families? fukking socket wrenches man. That's right. Socket wrenches. Because if you buy a socket wrench and get mad at your wife, then there's a chance you may throw it at her face and crack her fukking skull."
You get what I'm saying? Alcohol isn't sold for the sheer purpose of being misused or abused. It's not the alcohol itself that ruins families -- it's abuse and chemical dependency on alcohol. You misuse alcohol and fukk your life up. Use it properly and in moderation, and you don't ruin anything.
There's no "proper way" to use incest. It, by definition, destroys the family.
I can follow my argument just fine. It's not my fault that you can't. I'm done talking to this brick wall.
