It's myopic. Centered on, and informed by, a political culture that is quite unique to the US, and to a limited extent the UK. Lots of politics the world over does not work like that, and is in fact rooted in collaboration rather than "combat".
I'm in Denmark, and we just held local elections the other day. The overwhelming majority of city councils have broad constitutions across not just party lines, but across the entire left/right spectrum. It doesn't mean that there isn't competition, but it does mean that everyone is aware that they will have to work together with their competition when the election is over. This is the norm in most European countries with functioning democracies.
The US political culture is an outlier, and it is not useful to draw any conclusions about humans, politics, or democracy from it.
