If so, those people are foolish. Aesthetics and moral fashions (of this kind) come and go, but your body's health is for life.
BTW: The majority of people where? Where do you see this? The internet (which parts)? A middle class neighborhood in a small Midwestern town? An upper class neighborhood in a cosmopolitan European city? Culture varies tremendously so "where" matters if you make assertions like "the majority of people" think this or that.
Regardless of what you think people think, I'm telling you what they _should_ think which is more timeless and objective, since it's about medical facts that were true 2000 years ago as they are now.
I would argue that for majority of the people who talk about it does not. The goal is aesthetic and moral.
