Activist group, Pro-Animal Denver, has petitioned the City of Denver to place a referendum before voters in 2024 to ban slaughterhouses within city limits. Other organizations have attempted the same objective with voters rejecting the proposition. The question arises as to whether the petitioner is pro-animal or effectively pro-vegan, attempting to superimpose their lifestyle on consumers.

Pro-Animal Denver is specifically targeting Superior Farms that processes lambs with a 70-year history of operation both in Denver, CO and Dixon, CA.
