To be fair to people who are offended by this, the weight of the criminal seems entirely irrelevant so it's pretty obvious that the intention was to rile people up.
@kajib@Cold_Brew_Enema literally they are just fat. It's not anyone's business besides their own. That the original story/post makes note of them as even "high calorie" is ridiculous too
There are some that consider the term obese to be derogatory.
I don't agree with that opinion, but I can understand where they come from. I generally support body positivity with a heavy dose of realism. Being overweight shouldn't be a reason for someone to treat you poorly, but pushing the idea that being overweight isn't unhealthy is where I draw the line.
If I were medically overweight I'm sure I would also not like any term that directly points to something considered a very negative trait, however clinical the word is.
