Forrest is one of my favourite fighters - i'm gutted that Anderson made him look like a disabled donkey. Literally gutted.
Basically, i would love to find a reason to fault Silva. But there isnt any. He is a genius - watching his stand up is poetry in motion. And what you percieved as 'disrespect' was just an example of this genius.
Also, as others have noted, Anderson is one of the most respectful fighters in the game. But like others have said, i couldnt really give a shit whether they are or they arent trying to hug each other all the time.
