If the disagreement with gore is that he has said arrogantly that he can disprove evolution using the egg laying to live bearing example, then you may have a point.
However, I think he has more successfully demonstrated the difficulty and UNLIKELIHOOD of this transformation's having occurred than you have demonstrated that it did. I don't think there is much credibility in phrases like "cobbled together" or "this is what could have happened".
First, saying "it's enormous, it doesn't seem believable" is not a "proof", it's an appeal to emotion.
No it is not an appeal to emotion to say that the problem appears too large for the solution proposed. It is an appeal to logic and rational thought.
It does prove, however, that certain intermediate stages are truly workable,
I think this is too great a leap. The potential viability of certain stages observed in one species as a possible transitional form in another species is far from demonstrating that it was such an intermediate stage.
You have an inside track. Maybe you can get G3K to write this 1000 times in hopes he can save his mind and move on to the next grade.
