Yep, lets not go there.
The dayak/madurese conflict proofs that old habits don't disappear that easily.
And as much as I would rather not see such violent conflicts, regardless the time and place, one can not overlook the devastating effects of the heads being taken.
As in old times people where struck with fear and awe and it must have been a huge psychological weapon used by the dayaks.
(and than please excuse me for generalising the inhabitants of Kalimantan/Borneo under the name dayaks.)
I must say that the WW 2 headhunting raids appear more heroic in my humble western armchair point of view. (IMHWAPOV, that's a nice one
)
