This falls apart when you try to tell yourself that about a smoker, or a heroin addict, or even a cancer patient whose disease can still be fought with medical intervention.  Like sure, fatty, just eat yourself to death because you're clinically depressed I understand.  Maybe Dr. Kevorkian would've been down with that, though. Anyway, that's precisely when "fat-shaming" is most likely to save a self-destructing fatty's life.  As in "dude/girl, I knew you when you gave a fuck about yourself and I'm not going to stand by watching you commit slow-motion suicide or be the walking dead dependent on insulin and other medical intervention to keep you in that twilight zone between actually living and dying, bitch, fish or cut bait."     Years of being overweight and/or obese are as bad as being crackheads or long-term alchoholics -- they are miserable, undignified lifestyles and slow fucking deaths that also drag down the sanity and health and finances of the fatfucks' loved ones with them.  So if you won't give this kind of enabling sympathy to a stubborn drug addict, logic dictates you don't do it for a fat.  This is when you intervene with "tough love" and follow through with any help your time/sanity/finances can muster to shift a fatass loved one back to humanity, without being sucked down yourself if he/she doesn't want to be helped.
