Ethics has nothing to do with eating food.
Maybe we should turn the question on them.
“Explain why it is ethical to allow your children to be malnourished because you don’t eat meat.”
or
“Explain why it is ethical to eat living plants and their offspring, fruits? Just because they can’t move, or verbally express pain, why is it okay for humans to consider anything else their own personal food source?” Plants feel pain, and they also respond to positive and negative stimulus noises.
“Ethics has nothing to do with eating food.”
