You're probably correct, but it really is all about semantics.  Smokers are tobacco addicts and fatties are food addicts.  Both incur horrible health repercussions from their lifestyle choices.  There really is no substantive difference other than how society has chosen to demonize one and be sympathetic towards the other.  It just pisses me off because I lived through the period where the government and media really went out of their way to make pariahs out of smokers.  The anti-smoking poster in the collage illustrates how they actively tried to paint smokers as UGLY.  They didn't just try to depict the habit as undesirable, but the people themselves.  And it was effective propaganda.  But now we're forced to celebrate "plus-size" models and are called bullies for daring to suggest that cellulite is unattractive and unhealthy.  It just pisses me off.
