As a human maximalist, I could care less about what those cows think. The problem we face as a society is that too many of us are cow maximalist to the point we're prioritizing these cows lives over our own. Buying that cheese burger at McDonalds is a vote for more cows which has far more negative externalities than eating veggies.
The extinct elephant in the room is the fact that those cows are going to be slaughtered for food anyway.
