Just because a text book says it does not make it so. The world runs on the almighty buck and people have proven they will do anything to get it. So call it hogwash if you will, bury your head in the sand or quote text books, makes no difference to me, when it looks like a duck and quacks like a duck, it's a duck. All you have to do is read the labels to see the garbage that is in food, read up on what is being fed to our food supply whether it be animal of vegtable. It reeks of "duck". Common sense is severely lacking in society today. We know something is true but let somebody come along and tell us "the text books and my education don't say that and the majority of us are accepting it as gospel. No thank you!!
