Just as a point of information, Leslie Orgel isn't a woman.
For my tuppence worth, chirality is an important point but it is not the case that any prebiotic synthesis must yield a racemic product. Looking in the literature you will find many discussions and analyses of chiral symmetry breaking processes. I'm not sure why Orgel makes such a sweeping blanket statement since some of the work that prebiotic symmetry breaking hypotheses are based on, particularly the Frank chiral amplification model, have been around for some decades.
