I remember seeing a photo of a smiling Japanese Officer raising his sword to behead a kneeling, blindfolded Australian POW. The photo was carried hand to hand until it reached Allied hands. The reaction was not, "are we treating the Japs with sensitivity?"
Great anecdote. I think the enemy abroad and domestic is killing our sensitivity.
I remember how shocked I was when news of beheadings was still new. I now find a deep anger has replaced that sense of shock.
IMHO the day is coming soon when islam will reap (and regret) what it has sown.
