There are several rules you can apply to scrutinize your own consumption. "the least amount of harm", for example. And/or the lower forms of life are more acceptable to eat or breed for slaughter (for example, a cow is less ok to eat than lice). Most use a combination. I think hunted animals can be fine since it's necessary to keep wildlife populations in control. Some might disagree and that's okay by me. But if you're at the level were a cow is just as problematic to eat as a carrot would be, then I dont think you've made an honest effort to think through your choices.

For example, imagine that people have the choice to buy clothes from sweatshops or from a factory where the workers have rights and decent pay. We can discuss the choice from a lot of angles: maybe the sweatshop is good for the economy, maybe the good factory makes it money by slave labour further down the production line. Maybe maybe maybe - totally fine and something worth discussing. But if you're stance is "I like the sweatshop I like the clothes and it's fine." Then you're not really, honestly, engaging with the question and you're just covering up the dissonance.
