Since Thomas Moore wrote the novel Utopia, people have applied that name to any society that seemingly promise perfection. Everyone knows a Utopian society is impossible, but some have made their attempts through tight government control. Each attempt ended in suppressed liberties and sometimes massive loss of life. The Weather Underground of the 60's who had their version of Utopia for the USA, suggested that 14% of the population would never accept their world, and would have to be eliminated.
