Why are anti-Israelis incapable of criticising Israel without being anti-Semitic? You conflate anything and everything with expressing legitimate opinions.
India Willoughby suggested that Israel would poison a laughingstock of a foreign journalist for criticising them. That is unfounded and absurd, and shows paranoia against Israel. Finally, it is not remotely expressing a valid concern about Israel's actions. It's just anti-Semitic lunacy.
