Fencing does come with etiquette and just because you don't have knowledge of it doesn't give you the right to sit back and judge.

We don't need to know the specifics to know that throwing your mask is bad. And I can't believe that all that fist-punching hoo-ha after every point is part of fencing etiquette. Salute the president, salute your opponent, that's obviously etiquette, even if done perfunctorily these days.
Have you thought how dojo etiquette appears to someone without a martial arts background of some kind? It might look a little silly or stilted to people, but I think it would be perfectly obvious to anyone after watching several matches what the drill is. It would be equally obvious that there is no showboating, drama, protests, etc.
