The context: A Supreme Court nominee was asked to define “woman”, to which she responded, “I am not a biologist”.
This is a silly word game. Many things are easy to demarcate for some or most cases, but very difficult, if not impossible, to define on the boundary. Just because it’s easy to categorize you doesn’t mean that the boundary is easy to define.
(Self-centered, again.)
