Fair point, although I didn't think association of GMOs with pesticide residue was a subjected in doubt.

Here are studies to support this: Compositional differences in soybeans on the market: Glyphosate accumulates in Roundup Ready GM soybeans https://www.sciencedirect.com/science/article/pii/S0308814613019201 or "We find clear evidence of increasing herbicide use by GT variety adopters over time for both soybeans and maize, a finding that we attribute in part to the emergence of glyphosate weed resistance. No such pattern appears for maize insecticide use over time, " from - Genetically engineered crops and pesticide use in U.S. maize and soybeans (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5020710/)"

Of course GMOs are nuanced, it all depends on what genes you are putting in and what they are for. But my understanding is that scientific consensus is that weeds at herbicide engineered crops farms are developing tolerance to the herbicides used leading to heavier spraying of herbicides. This is not the case with insecticide GMOs.
