The so-called demonization of Israel isn't something that's happening for the sake of itself, nor is it a manifestation of anti-Semitism(although for some it undoubtedly is); instead, it's in direct response to Israel's occupations, its settlements, and its oppression and injustice towards the Palestinian 'people'. The Gaza situation is just one part of it - and not even a particularly large one if you consider all aspects collectively. And because of the internet and digital technology, the world becomes smaller every day, and its people(more educated and openminded than ever before in history), are becoming increasingly aware of what transpires well beyond the borders of their own countries - and actually giving a shit! The bottom line is that the 43 years you mention has been catching up with Israel at an accelerating pace over the last few years, and Netanyahu's fascist leaning coalition is accelerating it even further. What Bernard-Henri fails to understand is that no amount of 'talk' is going to stop the "demonization" until Israel stops the things that fuel it. That's its message to Israel: "it's time to stop".
