Playing cockfight in proxy is more better and preferred than having them play in physical, because the government agencies in charge of animal protection and health may not allow for this, they are also living things and should be well treated and not abused, because instigating them against each other to fight upon is somehow barbaric and i also don't support this kind of behavior on them, which i may not see the action the government is taking as something bad.
And since it's by proxy it even makes it more easier to gamble on, and the animal protection agency and there is a lot of people that are obviously against this kind of game feeling that they don't have to make two animals fight and since it's by proxy people might have interest. The government might even persecute who ever is caught. And cockfight have been happening for decades now have not experienced one but have seen it multiple times on TV but I wonder if it is actually real and since am more of football am not really bothered about the cockfight since everyone have what they like. And am sure most people will prefer soccer for sure.
