“Speciesism is morally objectionable because, like racism, sexism, and heterosexism, it links personhood with an irrelevant criterion. Those who reject speciesism are committed to rejecting racism, sexism, heterosexism, and other forms of discrimination as well.”

“We should always be clear that animal exploitation is wrong because it involves speciesism. And speciesism is wrong because, like racism, sexism, homophobia, anti-semitism, classism, and all other forms of human discrimination, speciesism involves violence inflicted on members of the moral community where that infliction of violence cannot be morally justified. But that means that those of us who oppose speciesism necessarily oppose discrimination against humans. It makes no sense to say that speciesism is wrong because it is like racism (or any other form of discrimination) but that we do not have a position about racism. We do. We should be opposed to it and we should always be clear about that.”

“..the struggle to end sexist oppression that focuses on destroying the cultural basis for such domination strengthens other liberation struggles. Individuals who fight for the eradication of sexism without struggles to end racism or classism undermine their own efforts. Individuals who fight for the eradication of racism or classism while supporting sexist oppression are helping to maintain the cultural basis of all forms of group oppression.”

“Homophobia is like racism and anti-Semitism and other forms of bigotry in that it seeks to dehumanize a large group of people, to deny their humanity, their dignity and personhood.”

“It was behaviour that I thought not far from racism, sexism or any other kind of prejudice or snobbery. 'Because you are not cute, I do not want to know you' was, to me, hardly different from suggesting 'because you are gay, I dislike you”

“Being vegan is easy. Are there social pressures that encourage you to continue to eat, wear, and use animal products? Of course there are. But in a patriarchal, racist, homophobic, and ableist society, there are social pressures to participate and engage in sexism, racism, homophobia, and ableism. At some point, you have to decide who you are and what matters morally to you. And once you decide that you regard victimizing vulnerable nonhumans is not morally acceptable, it is easy to go and stay vegan”
