Oh, on the migration issue, every UK political party is to blame, but the Left is the one that made this debate truly toxic.
Any notion of even curtailing immigration, any attempt to even start a neutral discussion on the topic has been for years systematically met by massive outcry, emotional blackmail, jumping straight at the jugular with accusations of racism, fascism, yadda, yadda, yadda.
The Tories have yapped a lot about it but in the end, in front of such hysterical opposition, they have never had the courage to do anything. They kicked the ball down the road, letting the sh*t hit the fan.
If the Left had been more open to a honest, neutral discussion about migration 20-15y ago or even after Brexit, Reform would have had no space to exist.
Between a white, male, pale and stale gammon from the Home Counties who doesn't like any foreigners because ..., and a Uni Leftie with blue hair from Goldsmiths who likes all foreigners because ..., there is no difference (and they often all come from the same socio-economical class in the end). Both have based their views on dogmas rather than critical thinking.
