This applies even if the criticism of Israel is unfounded or dumb. Eg if I said "I think President Macron is sneaking into my garden at night to piss on my roses" I might be unhinged but in and of itself it doesn't suggest Francophobia*
But India didn’t say an individual (Netanyahu/ Macron), he said a collective county (Israel/France). So by your own example, it would be like saying ‘I think the French are sneaking into my garden at night to piss on my roses’ which does certainly suggest an issue with the French.
At any rate, IW is a raving racist. He’s has history of being racist to individuals, very anti-immigration and of course, homophobic to boot. To suggest is criticising the attack Gaza (which has nothing to do with LoJ’s heartburn) instead of being anti-Semitic is a stretch by any means.
And certainly I think you can be critical of Israel but I wouldn’t for a second assume that criticism comes from the same place as IW.
