Basically the whole "kind" thing comes from people whose level of biological knowledge appears to be at "The Big Picture Book of Animals" that we all loved when we were 5 years old. In books like that frogs and toads get lumped together (if toads even get a mention) and the entire insect kingdom gets one page and three species if you are lucky. No wonder that some people find Noah's Ark possible.
Funny, statisticians have no problem with the concept.
So are you saying “A rat is a pig is a dog is a boy.”
