Animals kill other animals.
Animals eat other animals. What do they feed carnivorous animals at the zoo? .....other animals
When I see animals intentionally aborting their young, I may see the equivalence.
The entertainment factor in this story is pretty much the only difference. American zoos don’t let the kiddies see the handlers feed live fluffy bunnies and other assorted tidbits to the inhabitants of the zoo
Of course animals eat other animals.
Humans eat animals, too.
What you obviously don’t get is that making a show of cruelty to animals is barbaric.
Even the hunters I know wouldn’t throw a deer across a wall to drop many feet to a painful landing and then enjoy watching wild carnivores rip it to shreds.
People who enjoy this are the ones who also enjoy, or eventually will enjoy, hurting other people.
I’m as anti-abortion as a person can be but I can still see that this is a horrifying form of entertainment, problematic for a civilized people, and that it will contribute to the mentality which tolerates brutal practices like abortion.
