I sadly do not expect anyone to change their behaviors, but the next generation will understand. I emphasized the connection to smoking as the idea that smoking is bad for you has been ingrained into everyone after decades of social change (although tons of people still smoke). To use that as a springboard "Smoking causes cancer, but obesity is worse" seems like an effective way to push society forward. Obesity is our smoking revolution and in a few decades there will be full acceptance, but for now we have to fight back.
