Very philosophical that, but it's only what we have internally too...
We all vote for a party / leader, those that lose the election (or those voters) lose out in a democratic process. Their voice is then minimised, or not even heard.
Same with a union. If 10% of you don't want to strike (just for instance) but the majority do, then the democratic view of the Union is to strike, and you're objection is overruled.
In that sense, yes, if we have a view, take it to Europe and lose in any vote, then we lose. Same rules for the rest though, sometimes our view is shared by others and we win. Democracy innit?
