Thanks for the clarification.
To give him a chance looked up what else he has said on this. Here is recent article by him. So more considered piece without being under pressure from questions.
A year after the 7 October attack, the myth of ‘blood libel’ persists in the media coverage of Gaza violence
www.theguardian.com
And its clear he is accusing those marching now of the blood libel
An answer is that this Israeli government of hardline Zionists is pursuing an eliminationist strategy in Gaza. People like Netanyahu and Likud party are the heirs of Revisionist Zionism and others in his cabinet are even further to the right Zionists
The problem they have is that unlike 48 the Palestinians have no where to go. So are trapped in Gaza. This isn't stopping the wholesale destruction of infrastructure to make the land unliveable as part of that strategy.
And looks like now that IDF/ Israeli government are trying to clear north Gaza. In 48 the population would have fled into exile in another country. That option isn't available now.
So children are going to be killed in large numbers. Not because that's what Jews do. It's a product of years of dehumanisation of Palestinians in Israel/ Palestine.
His view is that the anger at Israel action is not based on rational explanation but hatred of Jews.
There is rational way to look at what is happening in Gaza now. The pronouncements of Israeli leaders and all the documents South Africa have assembled in its case against Israel for example. The past history of removal of Palestinians from their land by Zionist as well.
So yes there is an answer to his question.
