If there is no audible distortion to the sound, how can you tell if something is, "Too loud"?
I assume by the way you phrased your question, that you are referring to clipping distortion. There's more to "distortion" than just clipping. Technically speaking, any change to the original signal is distortion (as in , "you are 'distorting' the sound".)
The kind of distortion that is usually the culprit in The Loud War not clipping distortion (though that can often be introduced as well) but dynamics distortion. In order to squeeze every last dB of volume out of a mix, they flatten the mix volume-wise with excessive compression and/or limiting and bleed the life right out of the mix.
How much dynamic distortion is too much? When is a mix too loud? That's what ears are for.
The question is how far do you wish to distort the sound in the name of volume? Or put more succinctly, do you want to set volume with your ears or with your meters?
I'll let you in on two secrets: First, 90% of the people who are on the "more volume is better" side of the war are only partially doing so for the reason they say. The main reason they are making those kind of mixes is because they aren't very good at making a good-sounding high-dynamic mix. It's much harder technically and creatively to make a "pro-sounding" high dynamics mix than it is a "pro sounding" pancake. So they go the pancake route and justify it by saying "I gotta compete".
Second, in a world where all songs are flattened like a penny on the railroad tracks, the one song with the incredible dynamics is the one that will stand out. It's easy to compete if one has a fresh sound.
