I dunno. Not easy exactly, but people with T1D can have extremely full and active lives, maybe it can be easier than having T2DM.
Was that meant to be another 'joke'? You do realise that T2 generally affects people over the age of 40, so mostly beyond elite sports champion age anyway? I'm very happy for those people, but as well as maybe bringing inspiration to some folk with T1D, people like them can also be used as a stick to beat those with T1D who aren't in such a fortunate/privileged position as they are: "Well, if they can do it, you obviously just aren't trying".
I've had T1 for 21 years and I despise the 'jokes' too. People don't understand that it can adversely affect pretty much your entire body, and they don't actually care in any case. It's the nature of any hidden disability, that 'know-it-all psychic doctors' will denounce you as lazy and smugly declare that 'there's nothing wrong with them'.
I've heard people brush it off as 'their own fault' (not in quite those words) when somebody with T1 dies young - almost as if they had a button labelled 'keep living with no noticeable problems' but just couldn't be arsed to press it. It's widely assumed that, if you don't eat sweet things, you'll be fine; but if you give in and have chocolate at any point, you pretty much wanted to die.
Living with T1D is a bit like managing a strict financial budget, except that nothing is priced and you don't know how much your income will be. Of course, you can have an educated guess at both of them, but so many variables are waiting around the corner with a cosh to 'surprise' you and nullify your hard work, it seems thankless.
I don't like the way that everybody assumes that 'diabetes' = T2; but then I also hate the way that some people (with or without T1) try to make it into a competition: 'T1s are blameless and worthy but T2s are just fat/lazy/unhealthy/asking for it'. Aside from that being a grotesquely offensive oversimplification, how does it help anybody to feel better about their serious health condition by criticising other people with a related condition?
Also, it's not the main irritant by a long chalk, but the sheer number of people who will say "Ooh, I couldn't do that [inject myself] - I hate needles!!!" Lucky for me, then, that regularly stabbing myself was already my favourite hobby before I was diagnosed, so I didn't have a difficult or painful 'choice' to have to make....
It also gets rather tedious - as for anybody with chronic pain (whether from diabetes complications or anything else) - when ordinarily-healthy people will complain incessantly and dramatically to you about how much they're suffering when they get a short bout of temporary pain, when for you, that's just non-stop for the rest of your life. I'm guessing that full-time wheelchair users feel similarly when somebody sustains an injury, has to use a wheelchair for a week or two, and makes out like their life is the hardest that anybody could ever have to endure.
