Their fear has not been without a human cost.
There may be people who would benefit from GMO food, but there aren't any food products that are available only as GMO versions. This makes it a political problem, not a "you can't have it if there is no GMO".
And equating anti-GMOers with anti-vaxxers isn't a solution to any problem nor reasonable.
GMO foods are capable of addressing specific problems, like vitamin deficiencies. People should be offered that choice. Anti-GMO activists, like anti-vaxxers, are hurting people by denying them helpful scientific advances.
Who here do you see arguing to ban GMO? Perhaps I just haven't looked closely enough.
What I have seen is people call for more testing, without defining what's enough for them to be confident in results. I've also seen people call for labels, but only on GMOs. I think the former is a backdoor ban. The latter should be applied to all foods.
Still no reason to equate anti-GMOers with anti-vaxxers.
It's antivaxers' children the ones that suffer the most, but as long as they remain a minority, the risks of an epidemic getting out of control is very small.
And no, we are not going to eliminate infectious disease any time soon. AFAIK, the only disease we have "eliminated" in recorded history is small pox; and what that means is that maybe a dozen governments have their stash of samples that they can turn in biological weapons... all while the rest of us slowly breed resistance out of the gene pool.
Plus since we can't just off the anti-vaxxers or let their sprogs die, society bears the cost of dealing with the messes they create.
Anti-GMOers not eating GMO food doesn't hurt you, antivaxxers doing their thing does.
