People care about GMOs because of corporate control inherent in the concept, not because it's "engineering". If regular people could make GMO crops in their back yard then nobody would have a problem with it.
That's an especially nuanced take, to the point that it's the first time I've even encountered it. Nearly everyone I've met against GMOs seems to think the problem is that they're creating some kind of mutant plant that lacks "natural" elements, and will surely give us cancer. Of course there's anti-corporate sentiment but something is lost in the telephone game for many.
