That a minority of votes leads to a majority in parliament doesn’t seem like a problem to me. That’s just how it works, nothing wrong with that in itself. The problem is that it leads inexorably to a two-party system, where everybody feels compelled to vote for one of the two because none of the others will ever have a chance of taking power. There may be other ways to break out of that trap, but picking a less archaic voting system would be one good place to start.
