Care to cite a medical journal on that? Or are you making up a 'usual association' of a disease to make a point that flies in the face of a mountain of medical evidence?
Hey, people who eat a lot of sweets can get diabetes. Smokers can get lung cancer. Guess you would have no sympathy for them either?
No sympathy for anyone who has cancer from smoking who started smoking post about 1960 when everyone really did know that it caused cancer.
No sympathy with those with diabetes caused by deliberate diet choices after they were given the warnings in time to do something about it.
No sympathy for obese people in mobility scooters who ignored every warning and chose to eat crap beyond an age where it was forced down their throats by stupid parents.
No sympathy for anyone who made a lifestyle choice which affects them and their loved ones.
Huge sympathy for those indirectly and directly affected by selfish, arrogant, criminal behaviour leading to what is popularly, and in cases even correctly classified as a "disease". Their widows, their children, their parents, relatives forced to ruin their own lives by becoming carers, etc.
