You must run in different circles than I, most people I know have reduced their added sugar consumption. My point was that there has been a swelling wave of anti-sugar sentiment over the last decades and it's reach the point were even RFK loudly said sugar is bad. That's the opposite of "no one bat's an eye". Of course people will ignore all sorts of advice for all sorts of reasons, but the sentiment (as shown by the decline of added sugar consumption) is there, and growing.

The Coke Classic is still selling. Coke Zero has not replaced Classic. Both "no one bat's an eye" and your use of "most people" (even with the "I know" qualifier) are clearly extremes of both sides of the conversation being intentionally used. The fact that things like Diet, Zero, etc version of Coke and other soft drinks exist show people are paying attention to sugar. The fact that sugary products are still being purchased shows that not everyone has changed their habits.

Shouting extreme positions doesn't really move the conversation

I recall a discussion here recently whereupon the list of items eligible for nutrition assistance (food stamps) in the USA were changed to exclude unhealthy foods, especially those with added sugar. Which BTW affects poorer communities disproportionately with long-term health problems like diabetes.

Elimination of processed sugar is a good thing.

Despite this, the discussion quickly pivoted to "how dare you keep poor children from enjoying birthday cake".
