Marc Pieterse

Marc Pieterse (1965) is a Dutch vegan and animal-rights advocate who speaks out against systemic animal exploitation, including industrial farming, live animal transport, and the normalization of violence against non-human animals. His work focuses on exposing ethical inconsistencies in public debate and challenging narratives that frame animal suffering as inevitable or necessary.

With a background rooted in critical thinking and evidence-based argumentation, Marc engages actively in discussions on morality, bodily autonomy, and justice—both online and in public discourse. He rejects speciesism as an unexamined bias and argues for extending moral consideration beyond humans, grounded in sentience rather than convenience or tradition.

Marc’s advocacy is unapologetic but reasoned: he prioritizes facts, transparency, and intellectual honesty over sentimentality. Through interviews, debates, and social media, he aims to shift the conversation from comfort and habit toward accountability, ethical responsibility and the abolishment of any form of animal exploitation and unnecessary harm.

I am against:

All forms of animal slavery or exploitation
All forms of animal breeding and farming
All forms of hunting and fishing
All animal testing and experiments
All ‘sports’ where animals are used and exploited
All use of animals for entertainment or ‘rides’
Zoos (there should be more sanctuaries)
Aquariums
Animal ‘shows’ or beauty contests
Keeping wild animal species as pets should be forbidden
Many breeds of domesticated animals should cease to exist because they cause suffering for the animals or because they are violent by breed
