Nobody is going to start a smear campaign over a parking ticket. C'mon! Being political isn't a one-way ticket to indefinite detention in the UK either! We're not in a totalitarian dictatorship or police state, and the UK is still a functioning democracy. There are plenty of upstart politicians whose lives haven't ended; look at the UK Pirate Party! If I were to become an independent politician in the UK, or found a new party, I'd not live in fear of shadows coming to get me in the night because that fear would be wholly unfounded!
Someone also doesn't go from political candidate to homeless on a roundabout without there being something seriously wrong with them, possibly some kind of mental illness! Bear in mind, someone with a mental illness might still be capable of rational thought but might be deficient in other aspects of their functioning. Who is this wrecked political candidate, anyway?
The moment you start a campaign, you are a state target. The press will dig out dirt on you to start a smear campaign so they can push their corporate backers' agendas and the government will mark you as a trouble maker. at that point your life ends. One parking ticket and they will descend.
I've watched two people "end" this way. One of them is now the "crazy guy" who lives on the A4/A205 roundabout. He was one of the most credible and logical individuals I've ever met. Now people throw rubbish at him because they think it's funny.
The voting public are lost. They are too polarised to supporting the main two parties and the system is broken enough that a majority on either side is inevitable. The result is that the conservatives or labour will always win. Their agenda, despite words either way, is the same. We didn't vote them in - we watched the election theater at work.
You strike me as an idealist and I really wish this was possible but i don't think the system supports fair resolution.
To be honest, it's not a democracy any more. This is not what the majority want but they are unaware of the consequences of voting or don't care. Whoever holds their coloured flag will do and won't make them "outside the club" when it comes to social matters.
