Fats are delusional, they can get people to back off of things if they squeal for long enough but they don't even have an average effect on economics and how companies act, they have a below average effect (save for certain industries which cater primarily to them and already market to them.) Everyone isn't all inclusive, they're just good at acting like they let fats make a difference by putting them off with words (and probably some trough coupons) and then continuing to act like they always have because that's how free markets work. Once all the successful fats decide they're willing to lose money to prove a point... Oh, wait.  The first p  ffa  art was never an issue, most companies know where their bread is buttered and it's not by the butterhuffers, only niche fat people products ever strongly courted their market. The ones that aggressively try have either established themselves as a specialty store for the fats or are using it as a pet project that they don't mind losing money at/are going to run into the ground not change.  As to your second point, I happen to agree with you; however, from my limited knowledge of psychology I think the consensus disagrees, for most people... it's just monkey see, monkey do. They feel validated in their echo chambers and better about themselves because they see other dumpster fires all around them so they continue to pile on the food  pounds whatever. Edit: Upon reflection I definitely could have picked a better link but, meh, it's not a solid scientific foundation but if you keep looking into it elsewhere along the lines of "contagious obesity." I've definitely seen studies that people who see others eat more follow suit and vice versa and other similar things which drive at the point I'm circling.
