Gusts of hot desert wind drift through the broken window, shattered by a stone, in the house that Madonna Badillo shares with seven Venezuelan sex workers. Badillo fixed the window many times before but eventually gave up. Harassers have repeatedly hurled rocks at the home as an act of aggression against her and the transgender people taking refuge here. Since 2017, an estimated one million Venezuelans have fled to Colombia, leaving behind a crippling economic meltdown, political persecution and extreme medicine and food shortages.
