Genetically modified food producers don't want it to be labelled 'GMO' (or should it be 'GMF') Where are you on this issue?

a)By fighting the labelling, are they in a way, admitting that Genetically Modified Products are questionable, or does the reason they give for not wanting to label make sense to you?
b) In your area, have the non genetically modified products producers started labelling their products “Non GMO”, instead of waiting for the GMOers to label theirs?
