Sentiment against GMOs has been described by scientists as the equivalent of climate-change denialism on the left. (Anti-vaxxers cross political spectra.) Whether or not you agree with that, this NYT piece about one Hawaiian councilman’s attempt to get the facts about GMOs in the face of hysteria is well worth reading.
For me, it comes down to this: in general the science does not support the position that GMOs cause harm. There has been a lot of cherry-picking and misrepresenting of studies by people who are trying to ban GMOs. Either we trust the scientific community or we don’t: if we decide that they are untrustworthy on the issue of GMOs, why should we be any more willing to trust that climate-change is going on?
