So you don't think Livingstone or Shah have made anti-Semitic comments? Do we have to do this all again?
Hitler murdered those who didn't fit into his supremacist way of thinking and he is non-quotable in every respect. Livingstone is an idiot and is quite happy living a lovely lifestyle and pretending to be something he isn't. He is more equal than others and he knows what side his bread is buttered and who'll keep him in the manna. He's a complete fake.
Shah, pushed a further debate on Zionism that has been derailed and pounced upon by the right wing labourites (the blairites) who have no wish to counter aggression, racism and supremacist views because they find it uncomfortable. They like the middle ground and the rewards within it. Some are more equal than others.
