If you replace Jews with Muslims and include criticism of the Prophet, and this is exactly what EDL /BNP types say all the timeI got to question loads too, until I realised that questioning the Jews, WW1&2, and Zionism were always shot down and filed under 'taboo' or what not. The brainwashed reaction was always being labelled an anti-semite by society just for questioning, or worse yet, refusing to accept the narrative.
"Political correctness gone mad, can't even criticise them or you get labelled a racist /bigot"
