Are you just a selfish narcissist who thinks their pleasure is more important than anything else?
I’ve been a vegan for almost a decade, and I’ve finally started to see how self-entitled carnists are. How I used to be. I thought that I was entitled to the bodies of other living, sentient beings.
Maybe you should consider the possibility that some people in some aspects of life really are holier than thou and you could learn from them. Imagine someone pointing out to a serial killer how not killing is more moral and the killer answers with “Holier than thou.”. Would this be a good comeback?
This is not an equivalent situation, being vegan or vegetarian does not make you legitimately “holier than thou”. It is not a virtuous enough decision to be “holier” than the average person, and eating meat is not a bad enough action to be comparable to being a serial killer.
