I don’t see anything surprising in what you describe. It is well known that Zionism uses Judaism as a tool for its settler colonialism for well over a century now. The Bund wrote anti-zionist songs at the time.
Clearly, Judaism and Zionism are not synonyms, nor have they ever been.
It is the Zionist state of Israel that tries to present Judaism and Zionism as synonyms. We shouldn’t fall for Zionist propaganda / Israeli propaganda / Hasbara, call it as you want, these are synonyms. And this is why we need to call out both Zionism and antisemitism.
Saying that Israel is a theocracy (…) because this is what the Jewish religion is, not only is an uniformed statement, it is also an antisemitic one. Israel is a settler collonial theocracy because of Zionist principals. (And the support from the West - meaning, the decendents of the christians and/or europeans that were procecuting Jewish populations for centuries. I won’t expand on this now.)
Great. Recognising Palestine is one part of the equation. Of course, this is done too many decades too late.
The other part of the equation is Israel. Practically, what will the UK do to stop its Genocide and when? It looks like the UK still supplies millions of pounds worth of arms to Israel
Edit: Freezing Israeli Zionist assets sounds like a great option too to stop a Genocide. And the UK knows how to do this since around £25 billion of Russian assets are held there (see article).
