Sugar - here - covers more than just sucrose, especially when one of the more commonly used (and controversial) sweeteners is fructose, a monosaccharide.

Also, normal people (entirely correctly) call table sugar a carbohydrate. Why nerd snipe?

It’s not a nerd snipe. Some people or possibly all people digest monosaccharides and disaccharides differently.

Also, that might be a distinction without a difference in most cases, but sucrose and fructose also may not produce identical glycemic response to simple carbohydrates.

The point is this is a very complex topic, and some of it is at the edge of what humans know about nutrition.

It's precisely a carbohydrate.
