Reply to comment by WinBarr86 in ELI5- what is the difference between a liquid and a fluid? by stinkybuttttt

So are you saying that non-newtonian fluids aren't fluids?

No they are not liquids.

Amorphous solids are liquid solids. Liquids that are not fluid.

 amorphous solid is a liquid that does not flow: its atomic structure is disordered like that of a liquid but it is rigid and holds its shape like a solid.

Ok, but nobody said that all fluids are liquids, they said all liquids are fluids. Regardless of whether you're correct about non-newtonian fluids not being liquids, you haven't shown a liquid that is not a fluid.

Amorphous solids may share some similarities with liquids, but are still amorphous solids, hence solids.
