Crossfit + Diabetes

I have become more or less an expert on Diabetes. Type 1 in particular i do know about type 2 but i do not know what makes a type 2 diabetic tick.
Sticking with what i know. A TYPE 1 diabetic has a lifelong difficult uphill struggle to maintain their blood glucose levels. Type 1 is "known" as and autoimmune disease. No one knows exactly what triggers someones body to turn on itself. These people have to act think like one of the most complex organs in the human body.
So what is the formula? How does a human being act like a human organ?
It is all about the trifecta - Diet, exercise, and insulin. Take one of those out of the mix and the diabetic will fail, or even die. But what if we took away insulin? But instead we replaced it with intense broad and general fintess.
Replaced it with a 500meter row 20 renegade push ups and another 500 meter row.
Or replaced it with murph, nancy, diane, fran.
Would these people help others live their life without insulin?
My vision is EMMA not taking 3 insulin shots a day. I see her sucking on a juice box after or before a WOD, ringette game, jazz recital.
I have read that a crossfitter with type 1 in the states along with his diet only needs one shot of a long lasting insulin a day. His carb intake is very low and his exercise is plenty instense everyday.
Would you do Crossfit not to have to inject yourself everyday?
Would type 2 diabetes be such an epidemic? Would we be fat? Would we die, loose a leg, loose vision?
It pains me that most type 2 diabetics can prevent this from happening to them yet they continue on uneducated, unwilling to be better, and unwilling to care enough. And where Emma has no fucking choice in the matter.

I really want to hear/see your perspective in this because you all of course are the real experts on this.
Let me know if i am way off or hitting the mark fully or slightly.
I need to know. I need to keep my vision clear.
