This is true, since the terms are all what we humans use to try to categorize genetic differences. As we learn more, we keep redefining the terms we use. For example, the more we learn about the quality we call "intelligence," we find that some animals are not as "dumb" as we once assumed.
On the other hand, we find that the sub-species known as Marxist/Socialist, colloquially known as "liberal," is dumber than many animals. :)
YOu’re right, but for people like me, who weren’t keeping up when they changed the terms, it was a little difficult to catch up! ;)
