kappa, don't be fooled ... I mean, both pictures are totally ridiculous tribalism. The average of those people don't give a damn about the daily lives of people in Israel or Palestine. They just think in a way like "Israel and palestine is like occupier and the occupied, which is the same like UK occupying part of Ireland". That's all there is behind this displaying Israeli or Palestinian flags, there is no sincerely intended support for neither of both, but more a tribalist/self-pitying way of thinking. In the end, the average person there doesn't give a damn about what happens in Israel (I said "the average", of course exceptions exist). In my time in NI I saw plenty of Israeli flags in protestant areas and plenty of Palestinian and Basque flags in catholic areas. It is simple tribalism and by no means sincerely intended support for neither Israel nor Palestine.
And seriously, do you want that Israeli flag remotely close to a sign of the UDA? The UDA is a paramilitary organisation that caused a lot of violence, it is not that different from the IRA in that perspective and in a way not even that different from the likes of Hezbollah. Do you really want to feel even the tiniest sympathy for such an organisation just because they wave an Israeli flag (without really caring about Israel at all)? I wouldn't want the flag of my country anywhere near the signs of an organisation that sees violence as the solution to a conflict.
Also, maybe I should make a correction to my previous post: I am not saying the neighbourhood of the Oval is necessarily dangerous, I am just saying it looks rough and gives you an uncomfortable feeling when walking around there alone. I mean, violent murals that praise violence against the enemy, very dirty streets (including a set of streets of which only 1 house is populated and all others are abandoned), the docks very close by where at night nobody walks around ... It ain't the nicest part of Belfast, that's for sure.
