In a chemistry class I'm taking, one handout regarding denaturation of proteins gave a list of denaturants and how they worked.

Strong acids are described as interfering with hydrogen bonds. Why is this? it seems reasonable to me to think that hydronium would be able to form more hydrogen bonds than water, but I can't find anything online or in my course materials that talks about strong acids acting as solvents. The wikipedia article on polar protic solvents only lists weak acids. Is this because in strong acids the negative ion saturates the solution, thus not allowing the hydronium to act as a solvent? Am I just talking gibberish right now or fundamentally misunderstanding something, because I can find literally nothing about this anywhere (specifically, the action of hydronium in strong acid solutions as a polar solvent).
