Part of anti-semitism is assuming all of us think alike and agree with the article the OP posted. I don’t agree that Pro-Palestinian protesters are by and large antisemitic. I refuse to be afraid of them.
I am of the not in my name opinion, as are many other British Jews, including Francesca Newton who wrote this article on the 20th of October 2023 from which I have highlighted a few passages that resonate the most with me:
As a British Jew, I Say: Not in My Name

“In ever-growing numbers, British Jews are opposing the government's attempts to weaponise their grief for authoritarian ends by calling for a ceasefire — and protesting to end the mass murder of the Palestinian people.”
”Those who say criticism of the Israeli government or calling for Palestinians to live free lives is tantamount to anti-Jewish hatred imply that keeping other human beings in such conditions is somehow intrinsic to our Judaism. That implication is far more offensive to me than anything I have witnessed at a pro-Palestine rally.”
”It seems almost too obvious to state, but history makes it clear that Jews also need the protection of universal standards of human rights. Jews are not safe in a world that considers those rights mutable, apartheid acceptable, genocide justifiable.”
