Appreciate this read. However, doesn't the result in this case end up being trivial? "No matter how complex the subject, I can find a part we all agree on."

Appreciate this read. However, doesn't the result in this case end up being trivial? "No matter how complex the subject, I can find a part we all agree on." That's great, but it doesn't prove a meaningful notion of agreement about the whole, and I missed any argument that it could.
