It was an abrasive statement, but as a vegetarian who still loves cheese and eggs, there is a lot of truth in it. Much US large-scale farming harms the animals, workers, and environment. The animal feed land could be used for crops. Eating primarily meat and little else is not nutritionally complete. Large swaths of the rainforest are cut down to raise beef cattle. End of the day you are unnecessarily killing an innocent creature because it tastes good. People don’t want to hear these things, they want a bacon double double. They want waygu. That’s the cognitive dissonance that makes people mad. Again, I eat eggs that aren’t always ethically sourced and who knows about my delicious cheese, but I’m not getting up in arms trying to claim I’m still a great person when I’m wrist deep in queso.
