Well this is Friday evening here in UK and most practising Jews Jews won't be here until tomorrow evening.Also I don't know of any British Jews here, so I reluctantly feel I have to say something.
I grew up in London in a Jewish community, in the 1950s and 1960s.
I will give just a few of my memories.
Antisemitism was rife where I lived and many Jews were attacked on the street. I don't recall anyone being murdered though.
I remember at the age of 4 people shouting 'Go back to Israel'.
My father partnered with a Christian (a lay preacher) in opening homes for the poor in Hackney(London's east end). This preacher also happened to be black and some of the people used to shout 'Look at the Jew and the Black walking together'.
I was personally beaten up several times before I was 10 years. Once was because I killed Jesus, so I was told.(go figure!) Other times because of my school uniform, I suppose.
The police at that time did nothing, so some of our larger members formed a defence group which protected Jews going to prayer. (This was happening in several communities around the country, so I heard).
Both my primary and grammar schools were Jewish schools, so I had limited exposure to non-Jews in general.(Although some of my best friends/neighbours were Christian & Catholic ..lol)
When I was 18 I went to London university(Imperial College) and was asked to chair the Jewish society there, probably because I came from a Jewish school and had a good Jewish education and could easily get speakers.
During my first year there, I was astounded to find antisemitic literature spread all over the common rooms. Much of the literature came from Arab students. I particularly remember that relatives of Iraqi & Syrian leaders were there and were very active as well as right-wingers who were overtly antisemitic.(unlike the left-wingers(including 'Jews') who were more surreptitious.
I was threatened with a gun by the chair of The UN society, a Chinese guy called Sam(
@Sam -no you are not getting you gun back!!).
The staff at the university were unsupportive, including one Jewish professor.
I left for Israel, became a citizen, and stayed for 6 years, before travelling.
Later on(80s) I was back in London and joined a small group fighting racists (mainly skin-head types) with British Sikhs, Muslims.
