This is utter nonsense. Israel does murder children. It does destroy infrastructure, force others to live in squalor, and oppress them on the basis of their ethnicity. To respond to this with "well people also say racist things about Jews" is nonsensical; by your logic, the only way to avoid being an antisemite would be to pretend that Israel doesn't do things that it demonstrably does do. Accusations of antisemitism thereby become a sort of "get out of reality free" card, which I would argue is highly insulting to the many millions of Jews who have taken part in the struggle for Palestinian rights.
