Your "meh" is similar to disregarding contemporary environmental PFAS contamination because of historic lead contamination from tetraethyllead. "There exist bad things already" does not automatically make the additional potentially bad thing harmless. BT is sprayed on some food crops, but with GM food crops, it is contained within every cell of the plant, and cannot be washed off. You are consuming BT toxin, if you eat GM BT crops (the US EPA requires BT crops to be registered as pesticides). Putting poison in contact with mucus membranes seems, at the very least, 'possible' to have negative long-term health consequences. Non GM conventional crops can use systemic pesticides (the irrigation water contains the poison and/or the seed is pre-treated. This also incorporates the pesticide within plant tissues so it cannot be washed off). These systemic pesticides are usually neonicotinoids. Presence of systemic neonicotinoid use in conventional agriculture does not negate concerns about GM BT crops. My point was that GM, as it exists today, makes conventional agriculture's issues of pesticide exposure and low genetic diversity in our staple food crops worse, not that conventional agriculture doesn't already have issues.
