Question: If you could eliminate one mainstream Western ideology/movement, what would it be?
Answer: Probably individualism. In a globally integrated, fully interdependent world the unfounded belief that we are separated individuals is harmful, extremely dangerous. It makes us behave like cells, organs that were separated from the body and they believe they can exist in their own.
This belief leads to the self-destructive, ruthless and exclusive competition, success at the expense of others.
It is true that we are all unique, that we all have irreplaceable qualities, talents nobody else has. But we need to use them in a mutually responsible, mutually complementing manner in order to perfect the whole organism we are all but individual parts of.
