It is, but it's also entirely predictable.
With the left having shaped the debate around Palestine, and winning major concessions from the British government, we are now in a situation where the Israel lobby is happiest: where any criticism of Israel can be presented, always, as downstream of wanting to eliminate it. Anyone who criticises it, and its record, wants it to disappear.
This is the inevitable outcome of the Zionism is Racism motion. People can talk about its longer term impacts, and the conversations it opens, which I'm open to (and I think is probably true), but it was a tactical mistake. Some agreed/many agreed with it as a statement, but wanted strategic conversations about consequences and compromises. They were often told to just 'join the Tories'.
Any party that smothers strategic questions, however strange or counter-intuitive they seem (and I don't think that applies here), will lose. Strategy exists. It's a thing. It's why some businesses fail, and others succeed. It's why some people lead countries, and others are also-rans. To talk about strategy isn't about 'optics' mattering more than principles. Rather, it's a necessary pre-cursor to achieving your objectives. If you aren't at least interested in strategy - which depends on the constant ability to accept you may be wrong about something, being constantly paranoid about being mistaken - you will lose.
So rather than de-proscribing Palestine Action, or sanctions on Israel proper, we're here instead.
The framing of the question is absolutely insane
