Humans have a choice to box , play rugby , head a ball
Me chucking in my pretend metal little fish to trick a pike or perch or trout is playing on its natural instincts and I cannot argue that it has cruelty in it
Horses bred for racing are done for human entertainment , they don't have a choice
I am being devils advocate here , I know a lot of people enjoy racing , as they do fishing but we can't deny its not morally right
