Looks like you've actually confirmed that's exactly the case in your post. Iraq is your personal opinion. it has no connection to his achievements improving the lives of the sick and the poor, it has no connection to his policys which improved our standard of living.
If people want to have a go at him over Iraq then fine but they cant keep saying his government were just Torys then justify the criticism quoting Iraq.
Not directed at you but Tom Watson gave a magnificent speech defending Labours record during the party conference only for one person to shout Chilcot, the same person will probably be telling everyone they should be ashamed of themselves for not caring about the sick and the poor, to be honest it's sickening.
And to pursue that same logic, we should all be allowed to base our electoral opinions on issues that we care about. Europe encapsulates much of what I care about, even before the referendum, and even more so afterwards as the consequences became clearer. I'm internationalist, looking abroad as much as at home. I want a strong economy that is the basis of strong social foundations. I want no part of bigotry. I want regulations that take care of people, employees, products and the environment. All of that was encapsulated by our membership of the EU. And Corbyn sides with the Tories on this. So I can only conclude that on the economy, on internationalism, on liberalism, on rights, and on better social foundations, he sides with the Tories, and has little in common with me. And he has shown this in action, as recently as this year.
Since no one has any interest in electing a non-Tory government anyway, we might as well base our decisions on the issue(s) that matter to us. Whatever one might say about the Lib Dems, at present Labour are worse.
