Why do Pacquiao haters always have a way of discrediting whatever Pacquiao does?

They haven't fought and they already have one. This is ridiculous. Lets see what they're going to say if there is an upset. I am pretty sure they already have one stored. I notice it too and they were even jealous why Filipinos adored and admired Manny Pacquiao the way he was admired and not just mind their own business. These people was so busy looking at other people that they don't have time for themselves. Oh well, what can you do.
