Nice measured post.
I agree with you entirely. I don't think our democracy functions correctly and there are a number of ways to improve it - mainly to remove career politicians and castrate political party strength... but it's not time for a revolution - they're just enhancements to what we have.
Building on the foundations of what we have is the way forward - it's very much the successful British way - ripping it all down and trying to cobble it back together again is not the way.
That's a good point actually, I think I should have put "broadly happy". There are certainly things wrong with the government/society at the moment, but nothing that major that some minor campaigning/voting different shouldn't be able to sort out. There is certainly no need to destroy what we have to try and make some kind of utopia that will almost certainly not be much better.
