We have to be realistic. Did we learn nothing from history, our failure to realise what Hitler was doing, whilst talking to him? You cannot reason with psychopaths and committed murderers. Isis are something else: they torture, rape, murder, crucify, lie and steal: there is no sin they do not, or will not, commit. It is their goal to radicalise and to dominate other countries, to kill "non-believers," to destroy Western culture. So, what do you talk about?
Except that, of course, they aren't committing sins, they are doing gods work, just as Hitler was. Nothing scares us so much as devoted nutters, I know. How do we defeat them?
We either get drawn into the long, protracted barbarism of wars and skirmishes that they want, which guarantees that they have generation after generation of recruits who see themselves as victims. Or we can make a show of talking to them, make a show of being the 'purveyors of peace' whilst showing them a culture that isn't barbaric, cruel, degrading, regressive, repressive and demoralising.
We won't win a shooting war against a Jihad unless we commit genocide, but if we fight with free speech, burger bars, Hollywood films, emancipation, equal rights, universal education and modern amenities then support for the nutters will remain a fringe.
There will always be idiots, responding to them with idiocy only fuels the fire, justifies their idiocy and gives them the means to recruit more ignorant people to their savagery.
Yes we have to be alert, there are lines to draw in the sand, but once they are pushed back over the line you have to put the sword down and pick up the pen or you are no better than they.
