A book for you all: "One" by David Karp. This is about a society where equailty is enforced by religion and science and the story of a college professor who falls foul of the equality scrutineers.

Another is "Excession" by Iain M Banks.

This is set in a left wing wet dream of a galactic society, everyone in "The Culture" is pan sexual, polyamourous, athiestic and can change their biological sex by an act of will. Their dissidents are treated as mad people to be enlightened to the way society is.
