The customers of biotechnology companies are farmers (whose customers are food processing
corporations etc.), and most of them don't care about the end consumer either: they want a product that can fight (kill) insects,
as well
as other natural
organisms — called names like weeds etc..
Likewise, a liberal with distrust of big business is inclined to oppose genetically modified
organisms, not necessarily because of evidence, but because GMOs are often developed and sold by big
corporations, which are seen
as incongruent with egalitarian and communitarian mindset.
