I would argue the opposite. A single climate denier isnt much of a danger but a handfull of vax deniers can cause an outbreak. Here in the bay area we've already had pockets of outbreaks traced back to groups of anti-vaxxers which endanger whole communities.

GMO fear is less dangerous but does come with problems although the main issue is the general scince illiteracy and scare mongering that allows charlatans to flourish.
