On a side note - a Type 2 (non-insulin dependent) that does not take care of themselves can turn into a Type 1 (insulin dependent) as they progress down the rabbit hole of over stressing their body and organs.
While I do agree with the points you made in your post, I just wanted to point out that a T2 can not turn into a T1. A T2 that wears out their pancreas and requires insulin is just considered an insulin dependent Type 2.
As far as the discussion about Type 1's developing Type 2, I know that this concept is supported in the medical community, but I do disagree with it as a concept. Here's why: there are other physiological processes happening in long-term T1 Diabetics that can contribute to insulin resistance. One of these has to do with extra abdominal fat from high insulin doses (this can be seen even in non-overweight T1's). This metabolically active abdominal fat can cause insulin resistance - but is it really a result of poor lifestyle choices, or a result of years of taking higher insulin doses than would be necessary in a non-T1 person? In T1 women, insulin resistance can also be a result of PCOS, and the PCOS is a result of excess androgen production stimulated by hyperinsulinemia (lots of insulin from injection).
My point is this: there are several different ways that a T1 can develop insulin resistance. Most of them are a result of the large amounts of insulin we must take each day to keep our blood sugars within a healthy range. Yes, it certainly is possible that insulin resistance can be a result of obesity in a T1, but I think given the unique circumstances of insulin resistance in T1's, it's not really accurate to diagnose T1 insulin resistance as "Type 2".
I also don't see a problem with the fundraiser. I don't really know anyone who could eat 12 donuts anyway lol. I could eat 2, tops. I'd bolus for them and be fine.
