I think the trash talking is all for the wrong reasons though, so I agree that they shouldn't attack each other personally. Much better if Casimero will just zip his mouth and just respect his fellow Filipino here. Of course we love to hear them trash talk to promote the fight, but I don't know, I have a feeling that it seems they are trying to hard to do it, specially John Riel.
They are indeed trying so hard to sell this fight. I mean they're going to make a noise in social media even if it means that the trash talking is going too far as long as they can sell the fight.
They're both Filipinos so it's inevitable not to think they're not going to sell this fight unlike when they're fighting against other races. And so, this is the result.
I have seen boxers and fighters who trash talk too much during the pre-fight pres conference, but they're actually a nice person in real life.
