dear Island Man...
I think the arguement is that without an objective foundation (God's law) then all attempts to outline "moral regulations" are subject to the bias or lack of bias in those making the laws.
an extreme example might be that pedophiles(sp?)might get traction in their attempt to redefine that act as a sexual orientation...no better or worse than any other sexual orientation. Morality and a productive and considerate set of values becomes subjective...and before you know it every objection is met with the label "intolerant" until values and morality don't mean anything anymore...we can see this to some extent in society today in peoples objection to the teaching of islam. People object to the teaching of mohammad and the fact that he is held up as the exemplar of that faith. To draw attention to the things that he taught as objectionable to WESTERN values(as being the absolute will of allah for all mankind for all time) will result in being labeled intolerant. their "law" or morality and value system is subject to mohammad's teaching...not what is a commonly accepted western moral and value "platform". It's crazy...their "system" is flawed by our standards but already we have dropped the ball in MAINTAINING the system we had in place and so we as a society have to reap the consequences of the fact that we can not get the genie back in the bottle, so to speak. One persons freedom is another persons captivity.
