My love of dealing with atheists is because they are so totally wrong...but I can help them.
For a given definition of 'help', right? I'm so glad we're the arrogant ones...
I don't want to go too deep into the science because past experience tells me that it is too complicated for those who offer no protection against 'stale lymph'.
I shudder to think about the fortitude necessary to plumb the depths of your 'science'.
It builds up within us in many different ways as clearly shown by old hands deprived of keratin...and as you say, causes mayhem with our immune defenses.
How have you controlled for the natural variation in aging effects to determine that this gradual depletion of epidermal keratin expression is 'sin'-related? How have you quantified levels of 'sin' to determine your correlation? Where is your working?
Introducing a science that goes someway towards explaining it isn't a crime.
Given that all you've done so far is make vague promises, we'd actually have to determine if conspiracy to introduce 'science' was criminal.
This pure aqueous fluid is prepared in our kidneys and returned there for refreshment but like deep Biblical translation you need to have a working knowledge and not make spurious attacks on the presenter.
A quick search for kidneys ('kelayot') shows that the bulk of the thirty references are to do with the ritual disemboweling of animals, and the other five are various accounts of people suffering life-threatening injuries as a result of violence. I'm not sure exactly how you'd read that to find advanced endocrinology in there, but I suspect it would be pushing symbolic into some bollocks.
