“If GM food genes mix with non-GM food genes (and they have and will), the consumer won’t know it. Problem not solved.”
So much irrationality packed in to one sentence.
Why would the consumer not know?
You said it is known that the genes have mixed (”they have and will”).
You are contradicting yourself.
“So much irrationality packed in to one sentence. Why would the consumer not know?”
So much naivete and ignorance packed into one question. Growers and suppliers themselves don’t necessarily know about contamination events (for example, pollen from a GM crop blows into a field with non-GMO crops; GM animals mate with non-GMO animals), so how would the consumer know?
