There are a number of reasons why people may be against cannibals. Some may object to the practice on moral or ethical grounds, arguing that it is wrong to kill and eat another human being. Others may have practical concerns, such as the fear of contracting diseases from cannibals or the possibility of being eaten by them. Still others may simply find the idea of cannibalism repulsive. Whatever the reason, those who are against cannibals typically do not condone the practice in any way.
