People don't want GMOs because they've been force-fed propaganda by the anti-GMO crowd.. go ahead and place GMO labels on everything, and see how many people still oppose it when they find their favorite food with a GMO label on it.

Is this a well-funded crowd, full of large corporate support? What do they have to gain with their 'propaganda' exactly?
Just FYI, I used to do research where I spliced genes for a certain enzyme into yeast in order to study the enzymatic mechanism, so I'm not exactly uninformed.
