My point is, what's not sociopolitically allowed is discussing how personal choice as well as normalized systematic issues (e.g., urban food deserts) are killing us, slowly. It's unfashionable to suggest someone's weight is (ultimately) unhealthy. But the USA wants to have its cake and eat it too, literally. That's not working out. It's not sustainable.
Finally, not to get off topic but over the last couple of weeks there's been a thread or two on HN based on acticles suggesting the GDP and similar "classics" economic metrics are hiding underlying social issues. That is, for example, healthcare care contributes to the GDP (or whatever) but that healthcare is for diabetes, opioids, faltering mental health, etc. We're falling apart but not to worry the economy is doing just fine.
It's complicated. But to your point, the fact that some important topics are ofc limits isn't helping. Until that changes the status quo will continue.
