What does negative cohesion mean?
The best example of negative cohesion is using Hitler. Hitler
originally gained his support no because people were attracted by
his ideas, but because they had the same dislikes or fears. Hitler
gained support because some shared the Nazis fears/dislikes like
communism which is negative cohesion. The saying my enemies enemy
is my friend is a saying about negative cohesion.
So basically when people support each other because they share
dislikes, not necessarily agree with their ideas.
