Re: Only one question
"Decisions are made by the people who turned up."
Wrong. Decisions are made by people who learned how to keep themselves in power indefinitely by manipulating the general political climate to their favour by any means available, on a statistical level, until polls tell them they have sufficient electorate support to get re-elected - whether by pandering to the masses, scaremongering, attacking their rivals: it doesn't matter. They have no interest in anyone's individual vote, they are playing the game of large numbers that any successful politician knows how to play and win. Anything that makes you specifically vacillate is not their concern, only the stuff that sways large masses is - and they know what that stuff is and how to control it.
You, as an individual, decide nothing beyond when you want to ###k off. Sorry.
