Sociopaths hate being asked to be generous or to consider the wellbeing of others. Emotionally/psychologically it “hurts” them. Literally they have never crossed into the “OK, I’m now able/willing to share my toys” stage of childhood. They still resent being asked and like young children get angry at being pressed beyond their development stage.
Elsewhere I have suggested it might be possible to pin down a sociopath’s approximate age level (somewhere in the latency period) but their development is a very odd amalgam with some incredibly young traits. The above is one, another is their inability to differentiate between the self and the self’s emotional desires (to them these are not two things). Being emotionally thwarted is taken to be an attack on the self.
True adult Tea Partiers should take over the movement. I am sure there are many sincere members who seek to restore constitutional government and a true democracy that reflects the wishes of the citizens.
