30. the cry endotoxins are identical...

...and there is ZERO evidence of vertebrate toxicity. ZERO.

As for your second assertion, every gene is subject to random mutations, but they are infrequent, and putting CRY genes into plants does not increase their mutation rate at all. That leaves selection as the most likely reason that plants might not continue "producing proper BT toxin and nothing else into the indefinite future." What on Earth do you see as possible elements of the selective environment that might cause that? The only selection plants expressing Bt are under with regard to CRY loci is insect herbivory, so any selection would likely drive reciprocal defenses against resistance, and there is likewise no current evidence that's happening.
