fair enough....
sorry if i came across condescending....having come late into a debate that's spanned several days and a couple of threads I think you were just an unfortunate target of frustration - apologies
Edited to respond to edit...
Do you want to carry on? I thought you'd agreed to disagree
The statement you make would be agreed upon by the majority of people - it does shift the debate in two significant ways -
away from a measurable and quantifiable divisor (ie time) to an amorphous descriptor (consciously choose),
and also away from consensual sex where person A consciously chooses to have sex, but is not emotionally/physically mature enough for person B to morally rely upon their conscious choice.
Both shifts are required because an absolutist is unable to frame his argument in the time specific and quantifiable world...a personal descriptor such as "consciously choose" is rooted wholly in the subjective - immeasurable in any objective sense and a strange relative foundation for an absolute morality...
In any case, certainly there are certain areas of "morality" which enjoy strong general consensus - rape, child abuse incest and child murder. These are areas in which we come as close as we can to what one might term an absolute morality. I think it's a mistake however to actually talk in terms of absolute morality even in such extremes - there is no objective moral yardstick which exists independent of human consciousness against which acts however heinous can be measured - without recourse that is, to the supernatural. What we have instead is an individual processing such actions within his own consciousness. After processing one can arrive at a moral judgment - and that there should be broad agreement on stark issues should not be a surprise - we are after all influenced by bell-curve biological compunction and semi standardized societal influence. The absolutist is always forced into the starkest areas of humanity in order to "prove" absolute morality - but even here there is no proof beyond general consensus.
To choose the least morally abhorrent item on the list, that of incest - Haidt makes a case for moral judgment being like aesthetic judgment in the Happiness Hypothesis;
in studies a short story in which a brother and sister decide to have sex is read to students, who are then asked to comment on their reactions and their reasons why. Everyone will say that it's immoral, unacceptable. When pressed as to why, the standard answer is that it leads to children with genetic abnormalities - but he then points out that they used contraception. Rather than say "oh well, that's ok then." They search for other arguments - "it's going to harm their relationship" - he points out that it's made their relationship stronger, and most finally with no arguments left just conclude "i know it's wrong - but can't explain why."
here is a classic form of confabulation in action - the interpreter module of the brain is skilled at making up reasons for a belief, but those decisions often have already been made on a subconscious level - gut feelings, intuition and snap judgments happen constantly and automatically, and the interpretor simply serves as a justifier for those beliefs. That which we regard as moral is inseparable from the subjective in which it was formed - and just because moral relativists can often agree does not mean that morality should be regarded as absolute
