I don't think you made an honest effort to understand the parent's point. They are saying that the jurors might have been biased against Monsanto due to the widespread fear of GMO, and glyphosate being a symbol of that fear.
I can't speak to what was in the jurors' minds, but in my opinion that's backwards: it is concern about glyphosate that is primarily driving fear of GMOs. If we got rid of glyphosate, I for one would not have any problem with the other GMOs I am currently aware of, though I would of course reserve the option of objecting to specific GMOs I might learn about in the future.
> it is concern about glyphosate that is primarily driving fear of GMOs.
In my experience the two most common anti-GMO arguments that I hear are: A) that GMOs can be patented, which creates IP problems when they spread, and B) that somehow human-designed species might be less safe than natural ones due to unintended health consequences of the modifications (not really sure the rationale for that one.)
It’s important to point out that this case is about Roundup as a whole product, of which less than half is glyphosate, not just glyphosate. Some other posts here go over this in more detail.
