Which is all fair enough.
Like almost everyone I was at most dimly aware of Corbyn prior to his becoming leader of the Labour party but, at that point, one only had to look at his record as an MP - defying the whip 100’s of times, never contributing as a legislator or select committee member to wonder what sort of leader he would become.
Later on his affiliations with what most would recognise as terrorist organisations became apparent and, whatever hair splinting you wish to apply, you have to admit that they don’t look good for the leader of the country’s 2nd political party. As bad in many ways as the Tory ties to wealthy individuals and hedge funds.
He defines himself as a rebel - which is OK when you have an establishment to rebel against. It doesn’t always work out when you become the establishment and you try to rebel against yourself.
As I said above - the role of the opposition is to try to hold the government of the day to account. It can be difficult for an opposition to make much headway when the incumbent party has a large majority but we had a minority government, governing only with the grace of a supply & confidence agreement with the DUP and a significant minority of the country who’s views were increasingly ignored by the Tories.
As far as I can see the Labour party had a clear responsibility to champion the 48% and, largely because of Corbyn, it has singly failed in that responsibility.
So, when I say I’m not a fan - it is not about his IRA affections, or support for Hezbollah (though neither endear him to me) - it is about the role he has played in the Brexit induced damage that has been done, and continues to be done, to the UK.
And the evidence for that is plain.
