The black death was caused by a volcano and not by germs.

Pro's arguments are essentially: "1. ..There is only one disease.. ......The only disease that exists is called 'vitamin deficiency'. ...... All diseases are either the result of vitamin deficiency or food/chemical poisoning. . ..... All diseases are the result of vitamin deficiency. .....The particular vitamin deficiency determines the nature of the so called 'disease'." CON responds that Pro states "There is only one disease.." yet then says " All diseases are either the result of vitamin deficiency or food/chemical poisoning. ." The ONE disease has now become MANY diseases. This is a logical error of high magnitude. Further, while vitamin deficiency can be a diagnosis for many diseases ( e.g. scurvy and rickets ) , these types of diseases are only a small sub set of all diseases. Of 20 major types of disease, Pro's arguments only address at most 2. (1) "2. The medical system has been devised specifically to make money .... by deceiving you into thinking that disease is a complex and difficult problem of which only a doctor knows how to fix. " CON asks Pro to submit examples to back up this claim. "3. Disease first began when humans started to grow crops and drink cows milk. Prior to that, there would have been no diseases. When you eat too much grain foods you will develop a condition called 'leaky gut syndrome' which will allow your gut bacteria to enter your blood stream. " CON responds that a careful examination of Pro's statement demonstrates yet another lack of coherent logical ordering. Pro notes that eating grain allows BACTERIA to enter your bloodstream. Bacteria is NOT a "vitamin deficiency". "4.Volcanoes ....cause the sunlight to be partially blocked. . ..... When this happens, there will be massive starvation periods ......they will develop diabetic related problems. Symptoms may include - toes, fingers and nose will turn black due to lack of circulation and their lymth glands will become swollen. Thus, we have what is called the 'Black Death'." CON allows that some volcanoes can affect the food chain, however the symptoms of starvation are very different from those of the plague. Starvation symptoms are "The eyes begin to sink in and glassed over. The muscles begin to become smaller and muscle wasting sets in. One prominent sign in children is the belly begins to swell. Skin will loosen and turn pale in color, and there may be feet and ankle swelling." (2) This is very different from the plague symptoms "Lumps and swellings would cause internal bleeding, which led to blood in the urine, blood in the stool, and blood puddling under the skin. This resulted in black boils and spots all over the body. Everything that came out of the body smelled revolting, and people would suffer great pain before death, which could come as quickly as a week after contracting the disease." (3) "5. Thus, germs are a SECONDARY PHASE of the disease process. The PRIMARY CAUSE being vitamin deficiency and food poisoning." CON puts forth that the term "food poisoning" indicates the presence of an external agent. That external agent is the primary cause. "6. Grain food causes the gut to leak because the grain contains tiny razor sharp edges which cut and damage the lining of the gut." CON responds that the incidence of "leaky gut" is low.
