First of all I would like to make absolutely clear that this isn't an Israel-apologist thread, before anyone has a go at me. I've stated elsewhere that I find the actions of the Israeli government indefensible and I'm not interested in making excuses for them.
It's been raised a few times on the Israel-Palestine threads though that there are other atrocities happening in the region, some on a far bigger scale (the displacement and death toll from ISIS is enormous, including 40,000 members of a religious minority in Iraq currently under siege who will probably die in a matter of days without humanitarian assistance), that are only getting a fraction of the coverage that Gaza is. The response is generally that the Israel threads aren't the place to discuss those issues, which is fair enough, but I do think the disproportionate response is interesting and I'm curious as to where it comes from.
I've heard people explain it as anti-Semitism, which I'm sure some of it may well be, but my hunch is that it's to do with anti-Muslim/Arab feelings as well - people can shrug it off because they feel like it's 'typical' behaviour from Arabs, or that they can deal with their own conflicts and it doesn't concern us. I think maybe people see Israelis as more like 'us' in the West, perhaps because many are of European origin, and so hold them to higher standards. I don't have any evidence for that though, so I'd be interested to hear what other people think.
