Re: Government’s role is to provide the opportunity for massive advances in technology [..]
I think it's a little unfair to conflate Corbyn-flavoured democratic socialism with the nazis. He may struggle to say the word Israel due to his (to my mind errored) cosying up with radical Islamic elements that thrive off the suffering of the people of Palestine but that is a separate issue to the economy of the UK. I'm not aware of him having stated that Jewish people are responsible for our economic and social woes (please feel free to link to a quote to the contrary if I'm mistaken).
I don't trust politicians full stop and am happy to take the piss out of them (hell, they've been taking the piss out of us for years) but the nazi thing is a bit of a stretch.
