This, to me, is especially revealing when it comes to debate over PR. The assumption is clearly there that FPTP has deficiencies (which in itself is arguable, as I have said infintely more of the blame for the current malaise within politics lies with the party system), and yet the rather clearer deficiencies of the other systems (which, despite articul8's reaction, one of which is definately that you get small parties like the BNP gaining representation far beyond what is justifiable) are rarely highlighted.
The only assumption that anyone should have about FPTP is that the returned candidate should (or rather, must) go on to represent everyone, whether they voted for them or not, equally well in Parliament. Instead, we have advocates of PR (who are often people whose parties would directly gain from it being brought in) pretending that an electors vote is wasted, almost that the elector themself is not represented, based solely on the party of the electors choice not getting elected.
I am repeating myself here, but those of an independent mindset who support electoral reform are barking up the wrong tree. Fix the party system, not the electoral.
