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
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.
People say that being a vegan creates a social problem in that others may react negatively. But isnt that the case if you take a principled position on any issue, whether its racism, sexism, heterosexism, violence as a general matter—or speciesism? The key is to educate others about *why* you take the position.
Just as we reject racism, sexism, ageism, and heterosexism, we reject speciesism. The species of a sentient being is no more reason to deny the protection of this basic right than race, sex, age, or sexual orientation is a reason to deny membership in the human moral community to other humans.
