@matija yeah, it seems that there were many factors that converged. I guess we never know what might have been or might be especially instrumental per se in the rise of anti-democratic regimes. As we’re seeing now in the USA, even supposedly “stable” vote-for-one systems are vulnerable to the most basic kind of fragmentation, namely splitting in half.
I’m not sure how stable these systems are then, considering the bipolar oscillations of government. The same gridlocks that make legislature impotent appear in a more blatant form. To me, that means vote-for-one is even less desirable than previously imagined, since even its claim to purported stability is moot.
