>How influencers have legitimised anti-Semitism

No, but many journalists (like this one) do conflate anti-Semitism with critique to the actions of the state of Israel.

Translation: the democratisation of media has made it more difficult for Israeli lobbyists and their conservative and neoliberal cronies to control how Israel's actions in Palestine are viewed.

"Ayaan Hirsi Ali became a Dutch citizen by illegally emigrating from Kenya. She appeared on a blatantly anti-Islamic film produced by Theo van Gogh, and since then she has been fearful of the consequences. She continues to rehash her anti-Islamic statement, and is now taken on tour by organizations seeking to smear Muslims. She was one of the interviewees in The Third Jihad, an anti-Islamic film produced by The Clarion Fund." https://www.sourcewatch.org/index.php/Ayaan_Hirsi_Ali

"The Clarion Project (previously the “Clarion Fund”) is a nonprofit organization initially launched by neoconservative activists in the United States and rightwing Israelis that produces alarmist films and publications aimed at hyping the threat of “Radical Islam.”" https://militarist-monitor.org/profile/clarion_fund/
