Most GM crops fall into one of two categories: either engineered to resist chemical herbicides, or engineered to produce insecticides themselves. When herbicides are used on resistant crops, over time the weeds develop resistance, leading to the use of even more chemicals. Crops engineered to produce insecticides on the other hand produce toxins that are not only harmful to pests but other insects such as butterflies, moths and insect pollinators.

That would be a reason to be against specific uses of GMO technology. It is not a reason to be categorically anti-GMO.

The general arguments against GMO are entirely without merit, in my opinion. Moreover, their consequences are monstrous, imposing costs on the third world just so first worlders can practice a deplorable philosophical fetish (or, more banally, inflame anti-GMO passions as a kind of agricultural protectionism.)
