I think people get to hung up on slogans. All politicians use them and they are normally lies.Legal case in Germany is under way.
"The Public Prosecutor's Office confirmed on reports that investigations had been started against the 28-year-old El Ghazi: "According to our assessment, there is initial suspicion against the accused of disturbing the public peace by endorsing crimes in conjunction with incitement to hatred by disseminating content," said the public prosecutor's office."
(For the law book freaks on here it's §§ 130 and 140 StGB ;) )
Instead of using a silly rhyme, people who want to support a free Palestine could just say "I want a free state of Palestine".
In my understanding, intentionally using the ambiguous rhyme in the context of the 7 October Hamas attacks and IDF bombing in Gaza is a straight case of antisemitism.
People who don't want to wipe out Israel never would use that rhyme.
Free Palestine? Yes of course.
What I pay attention too is the facts on the ground. And the facts are that Palestinians have been squeezed into a constantly shrinking area of the land that was once theirs.
