I simply do not believe that the so-called health side is really composed of people who are solicitous about everyone else's health. I can't prove it, but my intuition is that all the strength on the "health" side of this war comes not from people who really care whether other people are healthy, but from people who don't like having to see fat people. They are concerned about their own aesthetic pleasures, and they think fat is ugly.
Can that really be true? That is not my sense at all. I would think that, if anything, it would be sort of the opposite: People want others to be fat so they feel better about themselves. But generally speaking, I think the main reason for the ban is that there are a bunch of authoritarian busybodies running things.
