I disagree that the rift is just based on ignorance. It certainly is not ignorance to say that autoimmune diabetes (Type 1 diabetes) and insulin-resistant diabetes (Type 2 diabetes) are fundamentally two different diseases with different genetics, causes, treatments, and potential cures. I think it is essential to differentiate between the two diseases. The problem of misdiagnosis of adult-onset Type 1 as Type 2 diabetes is enormous, and causes untold human suffering. Prior to the 1970s, researchers speculated that they were two different diseases, and in the 1970s when it was finally determined that Type 1 is autoimmune and Type 2 is not, it was confirmed that T1 and T2 are different diseases.
All that said, I loathe the approach of the "Civil War" article. Using the term "civil war" is sensationalist journalism and inflammatory. And the young woman who is first quoted is ANGRY and is taking her anger out on Type 2 diabetics, which is simply uncalled for. Yes, the two diseases share some common symptoms, but they fundamentally are two different diseases and in my opinion deserve different names.
