From campaigning for Aboriginal rights in Australia in the 1960s to attempting to arrest Robert Mugabe in 2001, Peter made a name for himself over a six-decade-long career as an international human rights and social justice activist, challenging preconceptions around transphobia, homophobia, and xenophobia around the world.

Peter reflects on how activism has changed from his early efforts in the 60s to now, harnessing social media as a tool for mobilizing a wider – previously unreachable – audience, and the unfortunate “bullhorns” it creates, which threaten that progress. He also shares how by challenging the status quo, he’s opened himself up to a near-daily barrage of violent threats — all of which must be taken seriously — and how he no longer believes in laws that would ban hateful speech.
