Taking responsibility for the tremendous surge in highly-calorific, ultra-processed food over the last forty years or so?
And these calories are in the water supply? No, the fat people choose to buy and eat that food. I'm on a 700C deficit right now, it's not very fun, but it works because I have the discipline to not order a pizza.
Right. Fat acceptance was created in response to the sentiment that you're expressing - that it is a moral failing (responsibility).
