It's called an "analogy". He didn't try to make them out to be the same. Personally, I feel it's an apt comparison and one that has occurred to me too many times. The fact that each field has its "own set of requirements, regulations, practice, and repercussions" is obvious to everyone. Perhaps a better way to respond to such an analogy is to explain how the similarities and differences make his analogy valid or invalid. That could be interesting and informative.
