Sorry to jar you with that "suicidal idiot" remark. It was intended to connote the following 3-step process:
So the Greens were good on step #1, but #2 was "idiotic" because they did not bother to find out #3. This is actually a classic logic trap (IRV sounds like it gets rid of 2-party domination, but actually it does not – that is what I mean by a "logic trap." It is an easy logic trap to extricate yourself from, though, if you just do the most incredibly simple research to find out what happened in the country – Australia – with by far the most IRV experience. But the logic trap is so appealing that the Greens did not bother to do that incredibly obvious square-one research.) And it was "suicidally" idiotic because their life as a viable political party is being sacrificed by making this wrong choice.
Remember, if you are a third party, built-in 2-party domination equals political death for you. Given that we are talking about your death – don't you think it is worth doing what it takes to understand this?
