Bonnardel is one of the founding members of the French journal Cahiers antispécistes ("Antispeciesist Notebooks") and of the events Veggie Pride, Les Estivales de la question animale ("The Summers of the Animal Question") and the march to close all slaughterhouses.

[1] His father's choice of political engagement inspired Bonnardel to take a different path, turning to individualist anarchism and leaving school early with the intention to live in a community and train, before getting involved in activist causes.

[2] In May 1989, along with David Olivier and three other activists, Bonnardel published Nous ne mangeons pas de viande pour ne pas tuer d'animaux ("We Do Not Eat Meat So We Do Not Kill Animals"), in response to discussions of vegetarianism in France.

Bonnardel compares this with the religious concept of woman existing for the sake of man, or the slaves for their masters and argues that all individual animals have an interest in living.

[1] Bonnardel is critical of humanism, describing it as a form of elitism centred on white men, arguing that "[h]umanism is racism, patriarchy, the education of children, slaughterhouses".
