The problem with GMO labeling is that the same people who now say "if it's safe, there's no harm in a neutral label" will latter say, "if it's not unhealthy, why are you being forced by law to put a label about it"?

I wouldn't mind GMO labels at all - hell, I'd buy primarily GMO-containing products on purpose, out of spite. But there's enough insanity going on about the labels we already have (e.g. E-numbers paranoia) that I don't think labeling GMOs will end well.
