I agree with you 99%, but would like to make a couple clarifications:

> Type I is genetic. If you have the faulty genes, you get it. Regardless of lifestyle, health, country and whatnot.

It is not entirely genetic. It is an auto-immune disease that has a complex, and not fully understood trigger mechanism. That said, type I diabetics still do not have any control over it.

> Type I is binary: you have it or you don't.

Generally true, with the exception of the "Honeymoon Phase" in which new diabetics will still produce small amounts of insulin for a year or two after onset.

That said, I agree with the sentiment all the way.
