You can separate the 2. Being anti gmo is being anti science. Decrying all GMO as bad, unhealthy, or whatever is as illogical as trying to make any blanket statement about any food. It just so happens that this one gets headlines.
We should be concerned about the businesses like Monsanto. But that is completely different.
Personally I have been trying to avoid any product that goes out of its way to claim “non gmo” because it just signals to me that they don’t care about sustainability and science.
It’s almost as bad (and sometimes worse) than the “organic” crap.
