Segregationist denotes a person who separates people or objects from a cluster.
Step-by-step explanation:
A segregationist sorts a heterogeneous mixture of population. The population can be plants, rocks, humans etc. Exposure, clustering, concentration and centralisation; these are different dimensions of segregation.
It is mostly done on the basis of dissimilarities and the segregationist identified the dissimilarities and sorts them into different categories. Many times, racial segregation is done amongst people, and this has been the reason for unrest in the country or state majority of times.
