You are stating that T2 is caused mostly by weight gain (as in subcutaneous fat).
Wrong. The reality is explained all over the forum, so I don't think it is necessary to explain it again here.
As for your comment on alcoholism - weird. Perhaps you are confusing NAFLD with AFLD. Trust me when I say that is almost as irritating as a T1 finds it when they are confused with a fat T2.
So, another judgemental and misinformed post then.
This website explains how alcohol can make some people develop insulin resistance leading to the diagnosis of type 2.

I have watched 3 relatives develop type 2 through drinking alcohol every week in large quantities and one has now died from end stage liver disease, the other 2 are taking oral medication to control the bg along with other med.
I also became great friends with a type 2 diabetic who was very overweight/obese and was so insulin resistant that huge doses of insulin by injection was needed and even that didnt work so U500 was obtained through special funding and I helped getting/support with a specialist for an insulin pump. My friend was diagnosed with NAFLD, a scared liver, huge rises in the CA19 and CA125 tumour markers in the bloodstream and a whole host of other serious medical problems affecting every organ more or less in the body from head to foot along with a leg ulcer - gangrene, retinopathy, neuropathy, incontinence. She needed a new body and her head transplanted on to it. The tumour markers revealed the possibilty of islet cancer. She died a few years ago leaving me devastated as I tried to deal with the financial mess she left because she had no family that wanted to take responsibilty.
