I wrote this post in TA and I felt I could post it here and get your responses and contributions. It is a discussion mainly between me and a fellow who claims to have a biochemistry background. We have had several exchanges but I have a feeling he doesn't read the responses we write since he goes back to the same arguments time and time again.
Here is the current state of the discussion. I trust that with your contributions many issues will get clarified. Where am wrong, please point it out to me so it is not repeated elsewhere. You can write your comments here or on the page but I think since am more interested in it than he is, here would be fine for me.
Thanks for taking your time to go through the comments [they are many] and making a comment.
