That's foolish. I don't understand why people forget how many beans and legumes are out there... so delicious.
yes i does seem that people dont think about things like that, also many falsely assume that many thing are not be vegan when they are...like most bread (most ppl i meet seem to think all bread is made with both egg and milk, i guess most have never baked) or unfrosted poptarts, potato chips, yeast, mushrooms, margarine, ect
Im pretty sure that people dont actually believe that vegans eat bricks but some sure seem to have a hard time imagining a vegan meal that isnt grass clippings
