In fact the Far-Right is their least threat:
/// CST recorded 1,652 antisemitic incidents last year across the UK, of which just 5 per cent showed clear evidence of far-right motivation. A survey of 16,500 Jews in 12 member states of the EU in 2018 (the biggest survey of Jewish people ever conducted worldwide) is more revealing. The survey recorded the most frequently mentioned categories of perpetrators of the most serious incidents of antisemitic harassment experienced by the respondents as follows: someone they did not know (31 per cent); someone with an extremist Muslim view (30 per cent); someone with a left-wing political view (21 per cent); a colleague from work or school/college (16 per cent); an acquaintance or friend (15 per cent); and someone with a right-wing political view (13 per cent). ///
