Can humans get rid of extremism once and for all?

What would a world without extremism look like?

Western democracy has been riddled by extremism for far too long.

There is now a noticeable shift in Western nations towards far-right politics and extremism.

This is highly dangerous as one recalls the political situation before WW2, and how Nazism ruined the world.

Everything must be done to change that.

But it requires a rethinking and reorientation of politics and democracy in the Western world and also in the rest of the world.
