No it's not anti-semitic in itself. But it's hypocritical.
- China annexed Tibet and bullies others into not recognising Taiwan, claiming it as its own.
- Russia annexed Crimea and (effectively) the Donetsk region of Ukraine.
- Jordan annexed the whole of the West Bank in 1948 yet no one said a word.
- You barely hear a squeak out of Labour/the Left on the Kurds, who want their own state and are therefore in a not dissimilar position to the Palestinians.
- A Labour government supported an invasion of Iraq, which even if it wasn't illegal (which it probably was) was totally immoral.
Some of us on here are asking the same question, without getting an answer. What is the obsession with Israel on the left? Because in the absence of any sensible answer, the stink of antisemitism hangs over it. And when a decent guy like you gets sucked into it, you start to see how the Nazis did a similar thing.
People in Nazi Germany had Jewish friends, colleagues, neighbours, employers and employees. But Hitler succeeded in convincing the Germans that these normal individuals they interacted with on a daily basis - some nice, decent people, some maybe not so nice - were somehow not individuals with their own characteristics but part of something they created a vision of as a sinister, malevolent movement controlled by a mysterious central hand ("World Jewry"). Well, for "World Jewry" these days, the code is "Zionist" or "Israel".
And Israel is a democracy (albeit one with plenty of faults) with all the functions you expect in a democracy, such as an independent judiciary, free press, toleration of dissent and wide political views, multicultural, offering complete freedom of religion, with regular elections under proportional representation, as well as being a highly developed, hi-tech industrial powerhouse. That's everything surely a progressive citizen should want?
Yet it's bordered by Gaza, run by Hamas which is a fascist, militaristic, undemocratic, religiously fundamental organisation, which doesn't tolerate any deviation from its narrow, illiberal view. Yet supposedly democratic and freedom loving people would seemingly prefer that. Simply no logic to that at all.
