Almost every person I know who is on the organic bandwagon are very insistent, despite the evidence I have provided them, that organic food uses no pesticides and is better for you because it's "natural" whereas GMOs are made by companies who only care about money and are not tested enough and even if they were tested enough they could still do something bad because "you never know".

Ultimately it comes down to an ignorance in how the farming process works and an ignorance in how genetics work when modifying plants either in a laboratory or though breading.

I've also never met a person who supports organic who also knew about the practice of using radioactivity to cause random mutations in organic farming.
