Being vegan is not difficult in the slightest. Other people are what is difficult. How can ANY ethical stance ever be “difficult”? I’ve also never found it difficult in the slightest to not be racist, sexist, or homophobic. What is difficult are racists, sexists, speciesists, and homophobes, and their never ending excuses for their participation in their chosen forms of violence.
That is actually surprisingly true. You have to make some healthier decisions sometimes, like choosing not to eat ice-cream but grab some sorbet instead, but usually I don’t feel bad at all because I know that while everyone else is feeling guilty about what they’re eating, I feel totally fine both healthfully and ethically.
