I have an assignment in class. My friend thinks it's cruel to make horse race but I disagree. So we have to have a debate in front of the class and the teacher decides who wins.

I do have some things but I could use some help. And I'm talking about HORSE RACING. Not what the owners do to them after the race or the habits they might pick up. I'm talking just about the racing part.

Here are some things that I already have.
- -They were built to run.
-They can get hurt running in the wild to.
-They need exercise.
-Having them run isn't cruel, there 1,100 pounds of muscle it's good for them to stay active

Please share your ideas.
Thanks
