Like every work of art, it’s full of politics:
- an equal-rights relationship, where both parents take responsibility for their children and housework
- children who are accepted like they are
- inclusive schools/kindergartens
- themes that touch on preserving nature, helping the disadvantaged and more
No wonder it triggers right-wingers.
Extreme politicians having more leverage, in situations where the lead of the majoritiy party is very thin, is actually very common in most democracies.
The specific stupidity of the American democracy is the „winner takes it all“ rule which leads to a two party system.
