The article's point is that generalizations about GMd foods are ignorant and each case needs to be evaluated on it's own merits and dangers.
It's very well sourced (though it does occasionally fall prey into cherry picking) to show cases of both positive impacts like GMO Papaya and Golden Rice and negative like increased RoundUp usage.
Would be great if public perception adopted this skepticism and questioned practices that aren't discussed for labeling like widespread Bt spray usage vs the GMO included one.
