Corbyn clearly hasn’t changed his opinion on anything in 40 years, despite the evidence that he is wrong on many accounts.
What are you some sort of expert on Corbyn who knows for a fact that he “hasn’t changed his opinion on anything in 40 years” ?
Corbyn is well known for saying “I’ve never met anyone who hasn’t been able to teach something”, so apart from anything else it’s fairly unlikely that he has exactly the same opinions today as he had 40 years ago.
And he has been proved right on quite a number of issues. He was right about Apartheid South Africa – unlike the Tories who claimed that Nelson Mandela was a terrorist. He was right when he claimed that gay men and women had the right to be treated equal – the Tories were wrong about Section 28. He was right about the need for more social/affordable housing – the Tories/New Labour were wrong about leaving housing to the markets. He was right to say that there needed to be a political solution to the problems of Northern Ireland – the Tories/Old Labour were wrong to believe that there could be a military solution. He was right to claim that the banks/finance sectors shouldn’t be left unregulated – the Tories/New Labour were wrong to claim that “light touch” regulation was all that was needed. He was right to oppose the privatisation of the railways – the Tories were wrong to claim that privatisation would be cheaper and reduce prices for customers. He was right that the UK shouldn’t adopt the Euro – federalist Tories/Labour/LibDens were wrong to claim that we should embrace it. He was right to claim that PFI in the NHS would be a costly mistake – New Labour were wrong to claim that it would provide value for money. He was right to call for a democratic secular Britian – the Tories/New Labour/LibDems were wrong to claim that a feudal House of Lords was democratic and that the head of the Church of England opening parliament was acceptable. He was right to oppose the Iraq War – the Tories/New Labour were wrong to claim that it would bring peace and stability to the region.
OK I’m getting bored now, that lot’s from the top of my head, but you get the picture – Corybn has been proved right quite a lot, yet despite the evidence, as you say, you want to pretend that he hasn’t been. Let me guess dragon……..you vote Tory ?
