There’s still the self consistency issue. Let’s say people get to know that I can eat meat if I got offered one instead of giving the meat to other monks or animals, then they would have the perception that this is not a strict vegan monk, he’s ok with anything. So the next time they prepare food, they wouldn’t mind adding minced meat into every dish, since I am strictly speaking not vegan. This in turn indirectly increases demand for meat.
Thus, what I can do now is to be consistent to help remove this possibility of indirect letting meat demand increase.
