> - GMO, again, same point above. "Sure you can have this great crop, no seeds". Again, GMO per say isn't bad, its the implementation that's bad. Why specifically is it bad? If you want non-GMO food you can just grow your own.
Because it increases the amount of pesticides used (or incorporates them directly into the plant where they can't be rinsed off) and pollutes the natural gene pool with artificial genes. The increased amounts of pesticide run off the field and mess up the rest of the ecosystem. Now you're seeing herbicide-resistant weeds come up in these fields.
Does this argument work without the "all pesticides are bad" assumption? I searched up bt gene's use in pesticides[1] and it looks pretty safe.

>and pollutes the natural gene pool with artificial genes
As opposed to the natural gene pool being constantly polluted by spontaneous mutations? Or is that fine because of the naturalistic fallacy?

AFAIK this is a non-issue except to the farmers. Resistance to whatever usually comes at a cost, so in the wild the superweeds will get out-competed by their non-resistant counterparts.
