As a T1 I try to be sensitive about this and not add to the burdens of blame and stereotyping that are loaded onto T2s. Frustrating thing for us in the T1 camp is that in the public mind "diabetes" is synonymous with T2, all the more so if you're an adult ("I thought only kids got that!" "Not true, and anyway guess what: kids grow up--who knew???"). Some of the insularity comes from decades of seeing hundreds of stories in the media about "diabetes" and knowing instantly "they're not talking about ME," and it does get annoying after a while. It's symptomatic of being a minority inside a minority I guess. One of the great things about TuD is that in encouraging people from both areas to interact it has opened my ears to this particular complaint about the T1 culture, for want of a better word, and has made me less insular than I used to be.
But it's still the case that the public remains largely oblivious to the distinction. People who are determined to unburden themselves of their blindingly uninformed "expertise" on these matters, frequently these days framed along the lines of "why are we all having to pay for your fat, indigent, junk-food eating lifestyle!!!" or the like are tarring us all with the same brush. I generally try to get across that a) the disease I have is not the one you're thinking of, and b) you're wrong about that one as well. But it's not always easy to to fight a two-front battle effectively, especially as I'm naturally a lot more familiar with the ground underlying the "a" part of the answer. And in the heat of discussion it's hard not to respond with just that part: "I have T1, it's an auto-immune disorder that has f***-all to do with lifestyle, so shut yer yap you ignorant pillock," which tends to leave the "b" part standing as if tacitly endorsing it. I certainly don't mean it that way--I certainly don't think of it that way--but I can see how it can seem that way to my T2 friends and I do try to avoid it.
I agree with @Judith_in_Portland that comparative misery is an infantile and pointless game. When people say to me "Oh, you've got the bad kind," I have no trouble saying I wasn't aware there was a good kind and explaining that there's evidence that some of the things taken as causes of T2 may actually be symptoms, and so on. But as far as comparison does go, I actually see it the other way around. I've said many times (both in discussions with PWD and otherwise) that T2 is in a lot of ways a much harder disease to deal with precisely because it doesn't land on you like an alien invasion the way T1 does, but can creep up on you so slowly and insidiously, and because it does tend to come on later in life when it's harder to change set patterns of behavior. I have no doubt whatever that if I were diagnosed with T2 at my age or even ten years ago I would absolutely suck at getting control of it.
