But what would replace FPTP? PR? All PR leads to is monthly re-elections, unstable coalitions and wacko parties coming into power (Nazis, anyone?). No electoral system, even the 'fair' ones, work like they should, yet democracy is dependant on them
It depends on the PR system used. Theres just far too many to count. Not all of them would require coalition governments, and one is even designed to produce strong governments while wasting 0 votes. Not that it will ever be implemented for out westminister elections.
I'd rather a party who actually got a lot of votes get seats as opposed to having a party who almost nobody wanted getting one, and thus increasing their say on important issues dispite their lack of popularity
Theres no two ways about it. For an individual seat, the party MUST win the majority in that constituency in order to gain the seat. On a national level the 'waste margin' problem is an issue. The remedy we've preferred to use so far is to redraw the constituency boundaries every few years.
However remember this. On a local/single constituency level, the party that wins the seat IS the party that the majority of people in that constituency wanted. I wouldn't much like the PR system we use for our MEPs, where we have multiple MEPs per region. I mean, which one do I talk to

.
furthermore theres the issue that in this 3 party state we're in, it'd be extremely rare for a party to recieve the majority of votes. More people don't want them in power than those who do, but the only remedy for this I can think of is PR, the issues of which have already been outlined
I'm not sure I understand your point here. The 'majority' is simply the party with the largest number of votes. I think you mean the situation where one party has the majority of votes, but when combining the number of people which voted for the alternatives, you have more votes as 'people who didn't vote for the winning party'. Ie Con:40 Lab:30 Lib:20 Other:10 (Winner Cons with 40%, however that means 60% of people didn't want them).
The issue you gave with PR, is just the effects of SOME pr systems. Voting systems for the UK was reviewed by Lord Jenkins(?) sometime in 1998, which resulted in the current voting systems for Europe, Scotland, Wales, and London Mayor. The system he suggested for westminister was AV+ - where you get two votes, one for a normal MP and another for a 'TopUp MP'. Very similar to FPTP, except the TopUp MPs fill the 'waste margin' thus making the system proportional. So in the last election, the Conservatives would have had another 10% of MP share entirely through TopUPs. (They may have even lost the 1992 election under AV+)
Which is perhaps in itself another downfall of our system, that the individual matters not, and makes no difference to the outcome of elections. But my issue here is with the man's theoretical power, not the power that he may actually hold. In theory, he could be the last push a party needs to win over a constituency, and that constituency could be the last push the party needs to come into power.
The issue your describing there is that of the swing constituency. Where the outcome is unsure so parties up the campaign level there, thus resulting in more attention for them and less for 'known outcomes'. This is why despite Labour almost always winning many seats in the North, you'll never see them campaigning here - being that the seats are all safe.
This indeed flies in the face of democracy, however it must be considered that the effects of which are only temporary at best. Once the election is over and the MP is in place, no one cares for another 4 years

. As voting behaviour becomes more volatile and people in the North East up their IQ (through death of the old miners) a little, you will see more swing constituencies and likely, a change in campaign strategy.
That aside, I don't believe that thousands or millions of people have the right to change how I live. If the country democratically passed a bill to have this day turned into "national 'let's burn down leo's house' day" (nothing personal, just an example :P) would you have no legitimate objection to that?
Democracy is a good check on power; but a bad method for making decisions.
I'd have little objection for that since the majority of people would have wanted for it. I'd hope at least they'd have a good reason though. The issue here being
why they decided that. Media influence?
Democracy is great for decision making where the decision is simple and not too open to influence from media, peer pressure, and campaigning etc. This is one reason why there isn't a single country on earth which is labelled "Democracy" (although Sweden comes close. Government by referendum lol. Have a cuppa, vote on bill. Go home, watch tv, get back up, vote on another bill... and so on). Most democratic countries are 'representative democracies'. That is to say, the democratic part is the voting of the people which you trust to represent your ideals for the next few years.
So you have the best of democracy, and the best of elites making decisions as a small collective

. Its not a bad system.
