I feel like the article is trying to suggest it's because of antisemitic bias but, I think it's just the same thing I was talking about before.
Cause du jour. Why are the public focussed on this and not the myriad other conflicts around the world? Because that's where focus has been drawn for now. And that's where it'll stay - until it's drawn somewhere else, for other reasons. Then Palestine will just be another colour on the ever-morphing "flag of support" and the marching will be for [insert tomorrow's all-consuming issue here].
It's not just the flag wavers of course... the vast majority of pro-Israel chatter will disappear long before the conflict ends as well. Out of the news cycle, out of mind. And of course there's the ever-glaring and oh-so-sad reality that most heavily pro-Israel commenters doing the rounds (on and offline
) don't really care about Israel all that much - they care about "sticking it to the libtards" - so when the flags are onto the next topic... the counter-warriors will be too.
