Hey, I know, let's not advertise anything that might tempt someone. No ads for cars people can't afford, might make the poor feel inadequate, how about no ads for make-up,might hurt some ugly person's feelings, wait maybe no ads for stores of any kind so no one buys something they don't need or can't afford.
Where do you stop? Kinda discriminating if you only pull the ads for fattening foods when there are ads for all those other things isn't it? The purpose of advertising is to get people to buy things you don't need. If you need it you'll buy it anyway, so no need to advertise, right? Why is food so much worse than those others?
If you want to help cure obesity quit giving people disability money so they can just stay home and eat more. Make them pay for their own medical care. Free medical care shouldn't be for self inflicted issues. You don't work, you don't eat. Best cure for obesity on the planet there is.
