You shouldn't put every raw vegan foodist in the same basket. Well informed vegans eat a considerable amount of fats from oils (coconut, olive oil), nuts (almonds, walnuts, cashews), seeds (sesame, hemp), avocados, coconuts, etc. because they know it's good for them :)
Concerning your views on diet types, the raw food vegan diet is unquestionably the healthiest diet for the human species, if you wish to debate on that don't mind msgin me :)
