Would honey and molasses be liquids or sugars in a bread formula?

They are definitely counted towards the sugar.

The simple part of the answer is hydration. The primary purpose of the liquid in dough is to hydrate the starch in the flour. Honey and molasses are pure sugars and contain no water. Even though their phase is liquid, they shouldn't be counted as a liquid for making bread. You can't hydrate a starch with sugar.

In fact, the "liquid" part in the bread formula should mean water. There are breads made with liquids other than water (e.g. milk), but these liquids are mostly water with something dissolved in it. A liquid with no water in it doesn't count at all for hydration. This includes honey and oil.

The more complex answer should consider two other effects of liquid in the bread formula. First, there is the dough consistency. Bread is about texture. A liquid dry ingredient will not hydrate the flour, but it will still reduce the viscosity of your dough. Big amounts of it will make a very soft dough which doesn't keep its shape well, has a big oven spring, and in general doesn't behave like classic lean dough. So a recipe containing lots of such an ingredient will still need an adjustment of the amount of hydrating liquid (like water) even though the ingredient (like honey) is considered dry.

The second effect of adding a dry liquid ingredient is that it will make your bread softer. First, you are introducing new molecules into the dough, which keep the gluten strands from finding each other. So you get a less sturdy gluten formation, resulting in a more cakelike bread (yes, cake is cakelike because it has sugar and fat). Also, baked bread loses water over time and gets hard, but sugar binds some of the lost water, and fat prevents the evaporation of the water. A stale enriched (=containing fat and sugar) bread is still stale, but very different in texture from a stale lean bread. So again, you might still want to adjust the amount of hydrating liquid downwards a bit because of this effect your dry ingredient will have on your recipe (or maybe not, if you view the effect as desirable).

I accidentally discovered a softer bread by adding honey. I forgot to reduce the water and had to add at least a cup (or so) of flour to stiffen it back up again. I never did get the former feel of the dough (making bread) but it turned out better (and softer) than expected. I still used sugar, but not as much as before. An accidental discovery.
