> a two-party system inevitably leads to extreme polarization
There isn't much difference in practice. German politics is extremely polarized, far moreso than in the UK where there's FPTP. Look at how the older political parties have reacted to the rise of the AfD and you won't see any of the famed coalition building that's supposed to make PR fair and reasonable. Instead you see bizarre dysfunctional coalitions, lots of illegal suppression tactics and a level of hysterical rhetoric that makes the USA look relaxed by comparison. Nor is it different elsewhere in Europe.
The left reacts badly to conservative pushback in any system, any country, any culture. These things transcend national boundaries. It doesn't matter what voting system you use. The results are always the same.
