No one really. I guess Broner, although i don't really hate him. Edit: Don't like the roiders...Shane Mosley, Evan Fields etc.
Floyd and all of TMT Stevenson Malinaggi Don George Broner Haye Khan Wilder Petersons Bellew Cleverly Dirrells Fury Quillen Mundine Lara Cotto Salido Rigo Ortiz Oquendo Thurman Brook Porter Joshua Eubank Garcia Spence Briggs Pulev Huck YPH Jeff Page Sullivan Barrera Harrison Jr Jermaine Taylor Russell Jr Breazeale Donaire Szpilka Gonzales Vasquez A bunch more but not known enough to really matter. I also hate basically all of those lady boys that fight at bantam and below. EDIT: After giving this some though I have come to the conclusion that I hate Ronda Rousey more than everyone on this list combined.
Khan is starting to get on my nerves. But, I don't really dislike any boxer. Whay they do is not easy. And I respect the sport. It's one of the toughest, if not the toughest.
