People don't like his person.....
People don't like his fighting style.

Doesn't make them haters.
To be a true hater is to deny his greatness as a fighter.
He does, after all, whatever he has to do to win fights.

As with all great fighters, he'll be more appreciated after he's gone.
That doesn't mean it isn't frustrating seeing him not pounce on the carcass when it's ready to be pounced on.
