"I disagree. Loads of people are obsessed with Israel in a way there are not about, say, Iraq, Egypt, Russia,China, etc. etc"
I would agree with this. I don't feel well informed enough to comment but I wonder (speculating here) if one reason for this focus obsession on Israel's perceived inhumane policies and practices is that the world sees the Jewish people as victims who were treated so very badly on such a gigantic systematic level - and that as victims of inhumane crimes they are expected not to inflict inhumane treatment on other ethnic groups.... not sure but this is what I have thought from time to time. But it is always easy to judge without walking in other people's shoes.
A little bit like the image of the vulnerable 'good refugee' grateful and keen to integrate in Eu society that was busted somewhat after the Cologne events on NYE. Some victims become perpetrators... that's human nature sadly.
Still, there is a hypocricy in the 'left' where some people deeply believe that they are the 'goodies' and beyond reproach in terms of being humane. IME this si definitely not so. Although i'm left-leaning myself it's quite funny that many people who are more 'conservative' in how they vote behave very humanely in day-to-day life making personal sacrifices to help others, whereas some lefties are all humane in theory but ever so selfish in their dealings with friend, family or indeed strangers in need. I definitely do not believe in the lefties = good , conservatives = selfish prats, that is nonsense. getting back to the op, maybe the labour party does not believe it has a problem with some of its representatives and members? Or is it all about the Muslim vote?
