Rahmaan Mohammadi was reported to Prevent by his teachers and investigated by counter-terrorism officers when aged 14 for wearing a Free Palestine badge to school. It is not antisemitic to say that Palestinian solidarity has been suppressed in the UK https://www.bbc.co.uk/news/av/uk-england-beds-bucks-herts-41442122/prevent-the-14-year-old-boy-singled-out-as-a-potential-radical
Take action to stop Israel's planned annexation of Palestinian land in the West Bank: https://www.palestinecampaign.org/speak-out-to-stop-annexation-now/
And donate to UNRWA's Covid-19 Response Appeal for Palestinian refugees https://donate.unrwa.org/covid-19/~my-donation
When I had it I found that in the case studies they gave the threshold for reporting far-right students was much higher (intent to commit acts of violence) than for Muslim students (expressing intolerant views in an essay)
A clarification since some have questioned the veracity of this story (which was reported in all major news outlets): Mohammadi’s school deny that he was reported for his Palestine solidarity activities but do not say why he was reported. https://www.lutontoday.co.uk/education/challney-boys-denies-claims-student-was-referred-prevent-wearing-free-palestine-badge-1267066
After he spoke out about his experience the right-wing website Harry’s Place dug up some pretty misguided social media posts of his from the time. There is no evidence that these were the reason why he was reported to Prevent though
