I sound like an EDL member. I'm snide. Give over Russ.
Eco's "hero" was a man who called himself 'Franchi' but whose real name was Edgardo Sogno. He was ultra right-wing so maybe Umberto Eco is a little short-sighted on this. Most neutral commentators equate the word "fascism" with the right.
And, as usual, you're deflecting as your own short-sightedness is laid bare. One of the reasons that people carry out attackes like this is to achieve matyrdom in either a religious or political sense, They also want to encourage large-scale polarisation so that Western society reacts negatively to Islam in general and Muslims personally. In turn, that will polarise the Muslim community to turn inwards and be much more defensive. And they hope that, eventually, will lead to a civil war between the two groups.
There's clear parallels to the situation in the Labour Party where people like Rachel Riley have been forced to confront who they really are, because they know that certain groups will never let them forget it. And your short-sightedness fails to see that when you're crying about "Blairite witch-hunts" it's about trying to achieve political martyrdom and looking to cause a political civil war, forgetting that it's those who have been shown to be antisemitic who have caused the offence and their the ones you'd be standing shoulder-to-shoulder in the trenches with.
That's what the people at Charlie Hebdo failed to understand in my view. No one of sound mind in any way condones killing people over cartoons but no one of sound mind should condone deliberately and knowingly carrying out actions that will cause deep offence to others. And while that happens the cycle will continue.
