Can't disagree with any of your post, apart from suggesting a rewording of your middle paragraph, hope you don't mind

A 5% threshold would hopefully instill some discipline and compromise.
Also, I'd like to think the left has grown out of the ridiculous splinter groups based on events in a far away country 100+ years ago...The People's Front of Judea type groups should be an irrelevance anyway. We'd have to see.

More ominous for the left might be disagreements around those liberal/cultural issues as you say. If those ever found expression in a political party, my guess would be that it wouldn't do well at all - that would then bust the myths that the likes of the Daily Mail pedal.
