I find I remain physically pained when attempting to come to terms with the notion that a person could express the belief that only genetically modified tomatoes have genes.
A person with no prior knowledge of the subject might read "genetically modified" as "modified to contain genes"
That would require them to understand what a "gene" was in order to know that "genetically modified" is intelligible as "contains genes". That in turn requires a working definition knowledge of what a "gene" is. Feh.
