Regarding obesity and other similar ills, it’s no surprise that people resent being told that having self-control is a possible method of counteracting it, because literally every other bit of propaganda (mostly corporate and corporate-affiliated, like the Fat Acceptance movement) is utterly devoted to denigrating and devaluing control of one’s actions and thoughts.
It’s understandable, then. When your entire environment and the zeitgeist at large is admonishing you to “do what feels good” and “why eat one, when you could eat two” the presence of someone who tells you that perhaps you should not do what your corporate overlords wish is seen as an oppressor.
I like the easy path, too, don’t read me wrong. But I’ll walk another path gladly when the easy path unquestionably harms me.
