Fuck you you little ignorant shit.
I have a very serious, crippling disease. I spend more than half of my day managing medical treatments, and I need frequent surgery to keep me alive and I still can barely walk - and not always even that. It consumes so much of my time I have weeks I can accomplish nothing but keeping the symptoms at bay.
Life as it is doesn't have a level playing field. Society doesn't have a level playing field. I'm a pariah, a joke to people around me - when they bother to acknowledge the hobbling cripple at all. Picking on the cripple is good fun - ignoring the cripple is what people do most of the time.
So take your just world fallacy and shove it up your ass. Life isn't fair.
