Their corruption, trough-feeding, billionaire tax exile backers etc is very well documented for all to see, as is a history of racism going way back beyond ‘Clandestine Chanel Commanders’, Theresa May’s ‘Go Home’ vans, Windrush, the widespread support of South African apartheid in the Thatcher era (‘Mandela: Terrorist’ t-shirts available from Oxbridge Conservative clubs etc), back through the unambiguous racial hatred of Enoch Powell, Smethwick and right into the days of human trafficking and slavery. All this is undeniable, it is just historical fact. No ‘conspiracy theory’ here at all. Attempts by people such as you to revise and deny is pure propaganda spin and you should be utterly ashamed.
From a personal perspective I lived through the destruction of the industrial north. I left school (a shit secondary, certainly no public school for me) straight onto Thatcher’s dole queue.
