...and I enjoy that implication. It's a catchy way to draw attention to the fact that there's no way to define a kind, other than how many you want to have as a result (since they must all fit in a fantastical wooden boat) or how emotionally dedicated you are to keeping homo separate from the apes. That these two seemingly absolute needs of creationists are so completely at odds is the reason why nobody can pin them down on the definition or identification.
