I’m not sure I get it, is the joke colonialism?

… and yet, you fall right into their trap!

It seems like you are talking past each other, thus validating their point. Talking is easy, getting understood seems to be much harder.

I’m not a doctor but my understanding of the topic is that it’s pretty clear : any soda is bad.

Sure, a Coke a week, in a cocktail or otherwise, does not matter much but AFAIK people who buy entire packs (as in the photo) drink sodas at every meal and that’s unhealthy over long term, no matter what brand or type of soda it is.

So assuming that’s a well known medical fact and people still do it, then one can say they do NOT care for their health, no?

Coke zero is worse for your health.

nobody who drinks Coke care for their health.
