I think our synapses are joined up in radically different ways. All the examples you give strengthen the case for PR in any system where the (majority) government gains power through getting a minority of the votes at a FPTP election. 68% of the electorate didn't vote for Cameron, and so in your version they have no say for 5 years, they have to put up with the Tory manifesto, bad luck. Only the people who voted Tory have a chance of having their 'single issue' debated. Under PR at least some of them would be represented in some way, we could even end up with a government which was voted for by more than half of the electorate! Radical! As for 'getting stuff done' compromise and negotiation between elected representatives is exactly what I want, it's the way grown ups work. Many would argue that the less government's get to do the better as well.
