On the other side of the coin, it's also not surprising that people who do not know much about something might feel threatened by it -- not exactly a groundbreaking discovery. That said, I have a strong scientific background and still find the idea of genetically modified food to be inhumane and abhorrent.
Anecdotally, it's kind of funny that many of the scientifically "ignorant" people I've met have better values and ethics than many scientists.
