What is "birding"? According to dictionary, it's breed, catch, or watch. Fishers fish, right? What is "to fish" really, though? To swim? To be a fish? I mean, you can't extrapolate it from the common verb as a rule, because that doesn't apply to "birding", does it?
So no, I don't think your over-simplification works.
This may sound like a weird take, but the upvotes and downvotes system is a good way of learning about what people accept and don't accept, and to help me understand people better. I'm autistic and had a sheltered history, and I'm also a novelist; and honestly seeing agrees and disagrees is really helpful for me. Most of the time they shouldn't be taken too seriously, of course; and you should have or develop enough awareness to understand when you're just plain valid, or when you actually might need to adjust your thinking.
