Croatia sang about urbanisation and the decline of the countryside.

Israel was 100% a political show no elaboration needed there.

Finland sang about no rules - anarchism.

Serbia was anti war, which is also a political position.

Then there’s all the feminist and queer themes like with Ukraine, Spain and Switzerland. Arguably not political, but then again neither should be Palestinians deserving human rights.

And these are just what comes to mind off the top of my head.
