Jair Bolsonaro, Brazil

Jair Bolsonaro is the first of two accused genocide doers on this list. That might seem like reason enough to not want to show up at a conference of people already pissed at him for the damage he’s unleashed in the Amazon and the risk it poses to the planet if the ecosystem collapses.
But he actually has a perfectly good reason to not go to Glasgow. An Italian town is offering him honorary citizenship. Who among us wouldn’t pass up this once-in-a-lifetime opportunity?
