Undesirable
Step-by-step explanation:
Society is seen as a complete living body in Durkheim's functionalist way of thought. As such, even the unwanted waste parts of a living organism are extremely important to overall function of the society and it simply cannot do away with them.
In functionalism the sum of all the constituents of the society are greater than its singular parts.
Thus, the overall cohesion of society is held together by unwanted elements in the society too.
