While I completely disagree with this, there is a fear based on reality that the GM crops will be in everything without choice or disclosure.

Is an example.
All gm products should be clearly labeled on the front of the package. But this would kill the sales.
So people respond with fear and aggression. GMO soy is in alot of shit now adays as soy is in a lot of shit as well.
There is also unhealthy processing...
