As I said, I'm not into debating with deniers. Might as well argue with Holocaust deniers. It's something so big and obvious, yet they say it can't happen - when it already did.
Simple fact: the things spoken of were socially unacceptable. This is what Farsailor was saying and I agree. He didn't say "They didn't happen". He said that they were not (publicly) acceptable. (So Orlion, take note - we are NOT saying that the people attempting to achieve the one are attempting to achieve the other.)
They were unacceptable and everybody from all walks of life said they would "never" happen. Yet they did. The attitude toward social morality - what is publicly acceptable - changes when there is not a rock-solid - religious - basis for maintaining it. (George Washington said that long before I did.)
So people who say that other changes will never happen (just because) are the people who have no reason. I can think of an extremely probable driving reason. Human desire. Lust. The worship of the individual, individual rights and taking an idea like "the pursuit of happiness" and making that central to the justification of anything at all. It's not about "logic" or "reason", so the constant complaints against "logical fallacies" in slippery slopes are irrelevant. No one is claiming that slippery slopes are logical constructions
per se. The slippery slope is a real thing that arises when one thing happens, making another thing, not logical, but more probable. The probability of another change becomes more likely and gradually enters the realm of the feasible. The gradual change(in public acceptance) from marriage, the family and sex as something holy to casual divorce, and from there to casual adultery, to sex outside of marriage, toleration of pornography in public, and homosexuality CAN be described as a slope, and a slippery one at that. I do see a direct connection, and am quite convinced that sex outside of marriage was impossible as long as divorce was difficult, but it became possible when divorce became easy. Acceptance of homosexual behavior was not possible as long as sex outside of marriage was unacceptable. "Same sex marriage", an oxymoron in my lexicon, was not possible until the public first tolerated homosexual behavior.
It may or may not be a "logical" chain of thought, but it certainly is a factual, not hypothetical one.
2 Prebe: I do not say that morality always goes in one direction. As Farsailor pointed out, it is going in a definite direction at this time and that is what I am speaking of. As to forgetting, I do not forget at all. I deny that the claimed hurt (the mere denial of legitimacy of homosexual relations - as something separate from crimes committed against people who suffer from same-sex attraction, which I condemn along with the rest of you) is actual hurt. The actual hurt, both spiritually and socially (and I believe physically as well) is in public acceptance of such relationships. And no, we are not "supposed" to hurt. I don't think in all these years that you've ever grasped the Eastern Christian understanding that sin is an illness to be healed, not a crime to be punished - not a mere breaking of arbitrary laws. We do not see ourselves as righteous and them as 'sinners'. We see ALL of us as sinners, the peculiar thing about this particular sin being that they seek public approval for it, and I think that MY sins ought to be publicly disapproved of - that I OUGHT to have to do them in secret (I ought not do them at all, of course). So it's just democratic application of something that we see to be a genuine ill.
I'd have to emphasize "publicly acceptable" a number of times, so as to eliminate discussion of the evils committed by despots as things nevertheless disapproved of by the public as not relevant to what is publicly acceptable.
One thing Vraith said I am totally on board with:
I hope they DO eliminate pedophilia-related things from any "mental illness" associated categories: cuz then they have no legally acceptable psychological defense to fall back on. The system works: they get punished for what they DO, not for how they FEEL.
Even from my standpoint, a spiritual illness is by no means necessarily a mental illness - although I can see how one could spring from the other, one is NOT the other as such.
But the real point to be hammered home is the one mentioned above. We know that people have always done things. There have always been things like adultery, homosexual acts, etc. But under Christendom - the geo-political reality for nearly two millenia, they were publicly unacceptable.
People said "This will never happen." Practically everyone asked did.
Yet those things happened. This is fact, not speculation. We now live with casual divorce, cohabitation and so on, right up to same-sex marriage, whereas 100 years ago we did not. (Casual divorce was just being advocated as an idea at that point; cohabitation (as something publicly acceptable) was still completely unthinkable. (My thanks to Prebe for supporting this point.)
So the fact that you think something impossible/unthinkable today in the moral sphere is no argument at all that it may not happen - for it already has, and it definitely happened gradually so it can definitely be described as a slope.
