The OP was taken from the following book, I believe.
On Killing: The Psychological Cost of Learning to Kill in War and Society. by Dave Grossman

I have as yet not read this but believe it to be very good to help understand the psychology behind 3 basic people types. Just remember there are overlapping between groups so there are no clear cut lines.

Australia politically is a Democracy. In reality it is a democratic- in appearance- socialist state at this time. eg. Our constitution states that no part of Aust. can be ceded or controll given to another country/foreign body. Yet we have world heritage listed areas. The UN controls/rules these and we administer them. Re the UN. For a UN resolution to be adopted by the US it has to go before and voted on by parliament. In Aust our Ambassador to UN just has to sign it, no debating it and voting on it by our elected reps. In Aust we live in a fools paradise at this time.
