And welcome as always! (I saw your repost - I'm glad to see the discussion continuing.) I think you've hit on the crux of the problem, with the GMO discussion, and so many other issues: the urge (media driven, or at least abetted) to make everything black and white; you 'fer us or agin us.'

And, and Elyssa pointed out below, I think a lot of the questions ARE being investigated, but that information doesn't get out (or can't get out amongst the hype; when you're all on a rant, who has time for facts?) and so people who are rationally concerned don't get a voice or access to information. It's a double, maybe triple bind. Ultimately, GMOs or not, I do know our food system is deeply broken, so perhaps the more productive approach is to focus on the larger issues involved with food.....
