There is a need to be logical, darling.
Firstly, politics is intertwined with every part of society. We are governed by it and hence if we have to challenge the existence of human of human rights, more often than not, the people who should be ensuring those rights are available to one and all, will, naturally, get involved. How you categorise it as in your imagination doesn't matter.
Secondly, why the feck is politics such a no-go zone for you and Zlatan? It's part of our lives. It impacts everyone. Hence, to turn a blind eye to it makes no sense. Fair enough to anyone who is scared of getting into those muddy waters, but if someone does, they certainly don't Zlatan or your permission to do so, and fair play to them for being active and vocal citizens of their country.
