I’m not sure what you mean by how am I comparing them. Do you mean how do I compare 1g of sugar to other sweeteners as a measure of harm, or do you mean it as a rhetorical “they aren’t comparable” comment? If the former, I don’t really need to. Artificial sweeteners do not have measurable harm on normal human consumption scales, where sugar does. If the later, they are comparable. Sugar has caused massive issues in out society and artificial sweeteners are a way to alleviate some of that harm without people dramatically changing.

I don’t promote sweet foods or drinks. I hardly drink or consume them. I rarely eat deserts, and when I do they’re on the much less sweet side. I also usually drink coffee and tea black, or with a tiny splash of milk (alternative). If I had my way, we wouldn’t have sweet foods/drinks everywhere. The current state is that we do though, and the best way to help things isn’t to convince people to not like sweet things, but to convince them they can consume sweet things but they should avoid sugar where possible.
