My basic issue with sweeping diet generalizations is that it often excludes many people. As someone who has this very problem, I am confused by the strange diets everyone is on. If only I had that choice! (I generally dissociate myself from vegetarians and their ilk because I loathe talking about it) Regarding the topic of too much protein, nutrition doesn't quite work that way. You can't go tick-tock on your diet just because you have too much protein today; you will need protein until the day you die. You also need suger, fat, salt, and yes, fiber. It's also quite wrong to say everyone could be on a vegetarian / vegan diet because you well know that it's quite dangerous if it isn't followed correctly, and lo and behold, the average American is overweight. We can sort of blame the new trend diets for the lack of fiber.
