Haha where's Went, this thread is for him
Sorry for the delay!
I personally believe vote is a very important but should not be the only way for citizens to take part in politics. I'd love to see parties having open discussions with supporters on a regular basis and even bringing up parts from their political manifesto up for debates and referendums. Having the party leader decide the political line all by themself, despite the legitimacy obtained by getting elected leader, is too authoritarian.
Voting should be optional, because there is nothing more dangerous than someone who votes by hearsay because he has to or else he'd be fined. We have enough with people who buy propaganda without asking or people who are so deeply ideologised they don't even consider switching to anybody else even if their leader goes and murders babies on the street. By keeping it voluntary we at least make sure that the people who don't care and would vote without understanding what they are doing are kept away.
But this doesn't mean I encourage that. I believe everybody should
at least do as Shenanigans told me the other day: "I never care about politics, but when the election gets near, it becomes my life for a month". When I was in Argentina, everybody talked about politics all the freaking day. Maybe that isn't healthy either, but it ensured that, come the day, everybody had an idea of what was going on and what they should vote for, and I admire that. There is nothing worse than someone who doesn't vote saying "well then if X fucks up, it's not my fault!" Yes, it's your fault for not caring enough to really understand what is going on. Even if not voting because you don't know shit about anything is better than buying the first ad that comes on TV, I still think people should make an effort to care because politics decide everything- including who you are allowed to marry or how much your dinner will cost you.
About political systems, I am 100% sure a proportional, multi-party parliamentary system (see: Israel) is much more representative than a two-party system like in the US, where you end up choosing the lesser of the evils. Currently in Spain we have three flavours of left-wing parties and two of right-wing, meaning you can vote for the party that is closer to your beliefs instead of going for the one who can stop the party you don't agree at all with. It's important the system is proportional though, despite having many parties, a majority system makes it so the British politics will remain a Labour-Conservative battle, and voting for the other parties is essentially wasting your vote, not just because they won't win, but because they will barely get any seats at all ever.
In turn, of course, a majority system like the British or the US helps "stability", because either party A rules or party B does. Of course, when there is a middleground (hung parliament, congress/president on different sides), chaos ensues since nobody knows what "compromise" means, they are just used to majorities imposing their rule with iron fist. Politics shouldn't be imposing a 4-year dictatorship though, so I'd rather go with fragmented parliaments that force politicians to debate and find compromises that represent the majority of the people- not just the biggest minority.
