I agree that the other person and I are going round and round... which is useless. Although I understand the point that everyone can derive protein from plant based diets, to be fully inclusive all diets must be considered. anecdotally I had a student who for allergy reasons he could only eat 5 items, one of which was grilled chicken (salt was ok, no pepper, no oil). I am fully on the side of inclusive diets, and although I may get attacked for defending animal protein on a vegan platform (I am not trolling) I have many happy vegan regulars who know that I prepare good, honest vegan dishes without prejudice (unlike the typical Ramsey style vegan hating ranting chef). All this to wrap up my original point: when dealing with students in a diverse environment they often will say one thing while acting completely opposite!
