I'm sure many people understand this but I'm going to say it anyway:

People who are anti-GM are skeptical about scientists' ability to predict all the consequences of their meddling in living genes and chemical balance of nature components.

The nature had millions of years of coming up with sustainable balance between growth and death.

I hope no one will argue that many of the priorities in our current scientific environment are short term individual benefits, whether it is political, wealth or recognition.

This is the basis of anti-GM folk mistrust, and not inability to detect that everything is chemicals and cross-pollination is a gene modification as well.
