Just two generations back, in the 1960s, mainstream Australian society shunned both unmarried pregnant women and also homosexuals. They were loathed, and it would have been considered reasonable for the local police to turn-a-blind eye should misfortune befall members of either group – should they be killed.

In my opinion, human-beings are not naturally hateful, though powerful institutions often look to squash dissent by turning the tribe against groups with certain characteristics – particularly those likely to possess special knowledge.
