I was the managing director of Buenos Aires Zoo. I resigned because I tried to transform it into a conservation centre for endangered species but couldn’t. There were these vegans who’d demonstrate in front of the zoo, shouting at the families who came in, calling them murderers . That damages veganism. People think: if this is veganism then I want no part of it. Not all vegans are like that, of course. But there are lots of people who develop a great empathy for domestic animals only. Many of them end up hating people and that’s a pathology: it’s not healthy.
