I am well aware of that situation. I am well-versed on many nations' forms and situations of governance. However, "kingmaker," parties are not always, or even usually, extremists, and, even if they are, there have been MANY instances of Heads-of-Government willing to make a show of conviction by engineering the fall of their own governments and gamble with the electorate rather than continue to take the crap of increasingly onerous demands from such a "kingmaker," party. Also, such a circumstance is an outlier problem compared to perpetual and consistent issue of "all-or-nothing," government in a two-party system. So, while you have incorrectly and embarrassingly misgauged my lack of knowledge of multi-party systems, it would SEEM your view of them focuses on bad stereotypes and unfortunate outliers, which seems to a viewpoint, when advocated, that only serves the status quo.
