Greenie – An extreme environmentalist, where ‘environment’ doesn’t necessarily include human beings. Often applicable to those pursuing political ideals under a cloak of green righteousness.
Namby Pamby or Lovie – Essentially the opposite of the tough, self-sufficient, practical, straightforward, pioneering character. These people shy away from direct confrontation ( but are often quick to complain anonymously to authority), are risk averse, wrap their children (and themselves) in cotton wool, cultivate a veneer of social caring, fear anything mentally or physically challenging, are easily swayed by social consensus of the moment.
