But we must not let them continue to play cockfighting because it involves the lives of animals.
Are you really serious about that?
Can we apply that argument to poultry chickens that were every day killed for human consumption? Or you will say that it's another story because people need to eat every day regardless if it's a chicken or not?
I don't understand why you are against cockfighting because it involves the "lives" of animals but enjoys eating a chicken meal.
There's no Science or Math there.
There is a huge difference between cockfighting and poultry chickens. Poultry chickens are butchered because they are for human sustainability, they are used for human consumption while cockfighting is purely used for entertainment. They both involved the lives of animals but the means of use is very different. Besides slaughtered chicken has quick death while cocks used in cockfighting have to undergo a longer gruesome death.
There is actually a science there to explain why cockfighting is frowned upon while butchering poultry chicken is tolerated. And there is a math that shows people who supports cockfighting and who don't.
But all in all, I think it depends on the people's preference but what makes the difference between how inhuman both cockfighting and chicken slaughter is being discussed in this thread.
