In your example just “giving them a haircut once a year” would be more humane, but your example is not reflective of the real world, and is a strawman of what I said. It is neither “just a haircut” nor “just a haircut”

What I said was “buying wool creates the conditions that make sheep require shearing” when you buy wool, you are funding another sheep being bred for that purpose. This is not the same as saying we should go out and exterminate all domesticated sheep.

Humane options would include selectively breeding sheep back to their previous state, and simply not allowing them to breed.

We’ve dug ourselves a deep hole here. The solution is not to double down and keep digging.
