Nobody likes the practice, the difference is that vegans take a moral stand and choose not to contribute to it, while meat eaters shrug it off and continue to pay the people committing those acts, because they’d rather cows get anally fisted and forcibly impregnated than drink a milk with a different flavour.
Why should people committing unjust acts be allowed to commit them in peace? Where is the peace for their victims if we do not speak up? The MLK quote seems entirely fitting.
