I don't really get the outrage about him appearing in public a day after testing positive though.
It's pretty likely it wasn't even a real positive, just one that he needed to get himself to AO. And even if it was positive, why would anyone expect a person with his views and his resources to isolate? He can quite clearly afford any fine that he may get, he will never be put in jail in Serbia and it would be ridiculous for him to quarantine given his views on COVID and pandemic.
Would be way stranger if he actually spent 5-6 days in complete isolation because of some test.
