This is a really good explanation of why those all too present “Bob/John/Joe/unlucky-name-of-the week has X amount of candy B; he eats Y amount. What does he have? Diabetes, Bob/John/Joe/unlucky-name-of-the week has diabetes” memes that tend to clog the diabetes tag which, guess what, people who actually have diabetes like to use, because it is a life-altering chronic illness that impacts most aspects of their lives.
My general mental response to those (besides blocking the tumblr user who posted one) is to immediately fantasize about tackling them and putting them in a headlock.
Note that I am attaching a content warning to this because it does reference rape jokes in order to point out that laughing about a disease that someone had no control over developing as if the person brought it on themself is a form of victim blaming.
