I so far haven't seen evidence that you are, either.
As you said, ideas have momentum. I'm not sure if it's an expression of human cognitive bias or human moral plasticity. But it is the case that talking about whether to torture a person makes torturing someone more likely. Because evil is especially intractable when it is banal.
But those are reasons not to have the conversation. At all. If that's what you believe, you shouldn't have resurrected the topic because it involves a secret man is "not ready to know."
None of this is a reason to decide that suffering does not add linearly. And that's the only interesting question in the hypo. Because everyone already agrees that choosing either would be immoral if there were no forced choice. And everything you say about choosing to torture is just as true about choosing to dust-speck, except that it is totally impossible for us to dust-speck, given our current capacities.
In short, you seem to want to avoid the question of linear-suffering entirely. That's why the criticism of "getting out of the issue" could have any bite at all.

Citation, please? I have seen evidence that this is true of actual instances of torture. I have also seen evidence that this is true of cases where a person has written "I will torture". I have never seen evidence to support the idea that discussing the notion of torture causes rise in the rates of torture-incidences. (I am giving the benefit of the doubt and assuming you do not mean this in the 'magical thinking' sense.)

For those not familiar with the topic, Torture vs. Dustspecks asks the question: "Would you prefer that one person be horribly tortured for fifty years without hope or rest, or that 3^^^3 people get dust specks in their eyes?"
Most of the discussion that I have noted on the topic takes one of two assumptions in deriving their answer to that question: I think of one as the 'linear additive' answer, which says that torture is the proper choice for the utilitarian consequentialist, because a single person can only suffer so much over a fifty year window, as compared to the incomprehensible number of individuals who suffer only minutely; the other I think of as the 'logarithmically additive' answer, which inverts the answer on the grounds that forms of suffering are not equal, and cannot be added as simple 'units'.
What I have never yet seen is something akin to the notion expressed in Ursula K LeGuin's The Ones Who Walk Away From Omelas.If you haven't read it, I won't spoil it for you.
I believe that any metric of consequence which takes into account only suffering when making the choice of "torture" vs. "dust specks" misses the point. There are consequences to such a choice that extend beyond the suffering inflicted; moral responsibility, standards of behavior that either choice makes acceptable, and so on. Any solution to the question which ignores these elements in making its decision might be useful in revealing one's views about the nature of cumulative suffering, but beyond that are of no value in making practical decisions -- they cannot be, as 'consequence' extends beyond the mere instantiation of a given choice -- the exact pain inflicted by either scenario -- into the kind of society that such a choice would result in.
While I myself tend towards the 'logarithmic' than the 'linear' additive view of suffering, even if I stipulate the linear additive view, I still cannot agree with the conclusion of torture over the dust speck, for the same reason why I do not condone torture even in the "ticking time bomb" scenario: I cannot accept the culture/society that would permit such a torture to exist. To arbitrarily select out one individual for maximal suffering in order to spare others a negligible amount would require a legal or moral framework that accepted such choices, and this violates the principle of individual self-determination -- a principle I have seen Less Wrong's community spend a great deal of time trying to consider how to incorporate into Friendliness solutions for AGI. We as a society already implement something similar to this, economically: we accept taxing everyone, even according to a graduated scheme. What we do not accept is enslaving 20% of the population to provide for the needs of the State.
If there is a flaw in my reasoning here, please enlighten me.
