Im pretty sure you yourself know how untrue that is. People who eat meat do so mainly out of habit. Habits get engraved in your personality in a way that your ego will defend them to the death. If anyone or anything tries to change your habits, your ego makes it feel like theyre trying to kill you.

Its not really their fault, they have all the necessary information right in front of their eyes but cant overcome the habit hurdle. This is basic human behavior and we shouldnt drive people into corners based on their weaknesses.
