"Globalise the intifada", along with "from the river to the sea" and basically any slogan that the pro Israel lobby doesn't like, is labelled by them as antisemitic/promoting violence against jews and then amplified by "concerned" politicians and media organisations. The concerns are so great that lawmakers/police are only to happy to close down free speech and shut down protests over a genocide by threatening/actual arrests.

Conversely we have UK citizens hopping on a plane to Israel, joining the IOF and shooting children in the head in Gaza, then hopping on a plane back to the UK. They then just carry on, living amongst us, as if nothing happened, in the full knowledge that they will not be held to account by the Uk authorities for anything that they have done.
