So I think I pointed this out on another thread, where the thinking of Bergoglio here is consistent with Vatican II's perspective on false religions, where there's some good "in" them. Jorge has repeatedly emphasized the positive elements in these relationships, e.g. "love", affection, kindness, etc. just as Vatican II emphasized the positive elements (and "truths") within various false religions. When you're blessing the sodomite couple, you're not blessing the sinful aspects of it, but the positive aspects of it ... as if those can be blessed in isolation. By these standards one could bless Satan, since philosophically evil is a privation of good, and pure evil cannot exist, and anything that exists has SOME measure of "good" in it.
So we have the claim that the couple are being blessed in quantum "good" and not in quantum sinners. Problem is that the term "couple" itself inherently entails the notion that these two could be "together" as they are, and when you bless the "couple", you're blessing the "union", which is intrinsically illicit and disordered. It's the same thing with false religions. Ah, yes, the Muslims believe in one God, so "part" of their religion is true, but the perverse framework and context in which that isolated "truth" exists distorts and perverts even their belief in one God.
It's also related to +Fellay's characterization of Vatican II as 95% Catholic, failing to take into account the context in which these truths are being re-presented.
But the overall context vitiates even the good or the true elements within a framework that's disordered, just as the evil of Satan vitiates his existence.
Nevertheless, because Jorge states that priests can bless the couple, that means you're blessing them not as in quantum individuals, but in quantum "couples", and the notion of their being a "couple" is intrinsically disordered, so you're blessing an evil.
I don't disagree that the Tucho porn is a bit of a side-show distraction, as the perversion of Tucho isn't a doctrinal matter per se, thought it does shed light on the thinking of Jorge to appoint such individuals to the highest positions in the Bergoglian Church while punishing those who show even a hint of orthodoxy.
