The high number of deaths for diabetics are a result of most diabetics being type 2, and most of those being anywhere from moderately overweight to morbidly obese. I am a T1 diabetic and weigh what I weighed when I graduated college 16 years ago. I make good choices on what I eat and exercise regularly. A T1 diabetic with well-controlled blood-sugar levels who is not overweight is less likely to die from Covid than a non-diabetic who is overweight. They weren't sure of that early on so suggested the vaccine for all T1's, but younger and healthier T1's did ok.
This is for another discussion, but it is truly unfortunate that despite what has happened with Covid (in addition to everything else) that we as a society continue to not only minimize the dangers of being overweight but now in some ways glorify it. It's not ok, it's prematurely killing people similarly to how smoking did a generation ago and it's taboo to discuss it because you are "fat shaming".
As for the rest, well I respect people making their own decisions. That is what I believe in not only for this, but for everything. No one should be shamed if they choose to get it, or choose to wear a mask. But no one should lose their jobs or be shamed if they choose not to.
But really what it comes down to, was that it was rushed earlier than previous types of vaccines and that it doesn't stop the spread, and that we were lied to about that part of it. If there was a vaccine that made it so you had an extremely small chance of getting it, I'd be more on board with getting it myself. But if you see value in it and think any potential risks are worth it for you I am all for you getting it.
