'The aims of Farage, Trump and Corbyn are very, very different.'
That is why I prefer Trump, then Farage, then Corbyn, but I prefer all three to the 172.
'The Establishment' is a term with no real meaning.'
Tell Owen Jones that. He spent a long time writing a book about it.
'Do you believe, simply, in destabilisation of the UK's (and US') institutions of governance?'
No, I am not an anarchist, I believe in a party winning power and forming a government which is why I vote.
'How do you feel about the hacking of Clinton's emails? And the targetting of voting apparatus in some US states?'
I think Hillary put some secrets of the United States at risk by storing emails and communications on unsecured servers and I think that seems negligent to me. It should not have happened and wouldn't if she had kept her communications secure. I agree with Trump that it is worrying about electronic voting and hackers because there is a possibility that some votes could possibly be rigged which wuld probably harm Trump's vote.
'Is that also 'anti-Establishment' and therefore good?'
No, the Establishment put the electronic voting machines in and awarded the contracts. I prefer paper ballots and minimal postal votes in order to minimize the possibility of elections being rigged.
