Yes, people do treat people with drug and alcohol problems better than they treat people who are fat. Flip on the tv, or go to any movie. How much money does Robert Downey Jr. make per film, even after years and years of spectacular drug addiction? And when’s the last time you saw funny and talented Delta Burke on tv?
There’s a very, very big difference.
Nobody’s asking for “extra helpings” of respect. The point is that they aren’t getting any at all. If you’re fat, you’re no longer human. Fat people in America are treated like either animals or criminals. They aren’t asking for extra, they’re just asking for the same basic right to live, work, shop, travel, etc., as everyone else.
