This is the difference https://twitter.com/guyverhofstadt/status/1098608083427827720?lang=en . Farage keeps trying to provoke the Europeans, Corbyn would have offered them a much ‘softer’ Brexit deal than May. You couldn’t possibly imagine Farage having such a meeting, because he wants to destroy relations with our closest allies at all costs.
Of course, no one is claiming that Corbyn is perfect. But if you keep demanding perfection, you are playing into the narrative of the very worst political actors who will use that to claim that ‘they are just as bad as anyone else’. Trump does that, so do Farage and Putin, and many others I am sure. Same argument goes for the racism among members.
