No, no. The point, as you've alluded to, was to make the battle unwinnable.
Labour were accused of antisemitism and were given two choices. Do option A and you're antisemitic. Do option B and you're antisemitic.
The 'redefinition' of antisemitism came from Jewish academics. The clarifications (extended examples) to IHRA were an attempt to embrace both IHRA, in full, and those extra examples. The 'antisemitism crisis' mob - led by Margaret Hodge, amongst others - pushed a narrative that held Labour (and Corbyn specifically) liable for antisemitism whether they did one thing or the other.
Oppressed minorities have the right to define what is offensive towards themselves. The oppressed minority disagreed within it's own ranks as to what was offensive. It was impossible to win.
Labour didn't pick the battle - they were drawn into it. Labour never had the choice to not fight it.
Labour needed to be seen doing something about antisemitism, rather than doing nothing. Trying to redefine definitions is nothing.
From yesterday's Jewish Chronicle -
***Thursday's by-election saw the SNP's majority overturned by Labour after Shanks won 17,845 votes, well ahead of the 8,399 votes returned for Scottish Nationalist candidate Katy Loudon.
Shanks, 35, said: “I’ve spent years working with different faith groups, particularly around Christian and Jewish relations.
“I know a lot of Jewish people and they were genuinely scared and hurt by the culture that had built up and that wasn’t being tackled by the leadership [under Corbyn].
“It was a deeply personal decision, I found that I found it difficult to look people in the eye who were Jewish and who genuinely couldn’t understand why I would remain in the party.
“It was that the party leadership at the highest levels weren’t tackling it. I took a personal decision to leave, which was incredibly difficult to do.”
After he quit in 2019, Shanks, a teacher, wrote in a blog post of Corbyn: “A party that has been woefully inadequate in tackling antisemitism time and time and time again does not have those values at its core.
“And aside from all that, it’s a party that seems oblivious to how utterly unelectable it has become.”***
