Let's not beat around the bush. Europeans hate Jews, always have, always will. My grandfather who survived the holocaust always said Europeans are born with it in their blood, but I never believed him until this past month. Now that there are a shit ton of Muslims living in Europe, it's even worse for Jews.
That's why no one in the west cares about Muslim on Muslim violence, it's quite clear. 
There certainly does seem to have to be Jews involved before people do care. I've long said that, as Nobby acknowledges. I used to mention - and still do! - the Palestine suburb of Yarmouk outside Damascus which was destroyed and starved by Assad's forces in the early part of the ongoing Syrian civil war. No one cared in the West. There was not a single demonstration on their behalf I believe. Not in London anyway. If anything 'Stop the War' liked Assad and supported his war against the civilian population of Syria.
There is a serious recrudescence of anti-semtitism too in Western Europe, that's clear. It has been clear for some time, but it becomes especially clear when Hamas and the Israeli government come to blows and European synagogues, Jewish schools, Jewish businesses suffer attack from anti-semites. It's even happened in America this time. Hitler gave anti-semitism a very bad name and therefore - apart from some Hitler nuts on the Far Right - most anti-semites now prefer to call themselves something else. That's progress of a kind, I suppose. But the thing is still there. Check Roger Waters today (or yesterday, I'm not sure). Shudder.
I think you're being too bleak though Red Guy. Jew-hatred does not come with "the blood", European or otherwise. It's taught and learnt. It comes with ideology and religion. Perversions of both, maybe (maybe not). And it's still a minority sport, thankfully.
As for Afghanistan and the removal of over a million refugees from Pakistan into the hands of the vicious Taliban, I really don't expect any demonstrations. I hope Kenny's Jacket is right and people are gearing up for the big one in Trafalgar Square or outside the Pakistani embassy. But I think he's being over-optimistic.
