Your friend was unable to lead a normal life in Ukraine. I have anecdotal stories of Polish Jews being stoned on the way to the synagogue in the 1930s. I have Jewish friends and acquaintances in the Manchester area. They have been traumatised by events since October. You brush this trauma aside. The mass immigration we have had since the Blair years has not helped.
His family were unable to lead a normal life in Ukraine because of the appalling antisemitism that prevailed there before Soviet times. Why do you think Jews supported the Communist Party in Britain so strongly in the 1930s? Progressive Jews remain in the forefront of opposition to Zionist atrocities in the UK and in Israel.
The fact that you now mention immigration since the Blair years gives a clue about your outlook.
