I hate both the Clippers and Rockets as well, but the Clippers clearly take the cake as my most hated team in the league (at least until the Lakers become relevant again.)
That said, I think I've narrowed down the reason: every single individual associated with the Clippers, with the exception of Doc Rivers, deserves to be slapped repeatedly in the face.
The old owner? Needs to be slapped.
The new owner? Needs to be slapped repeatedly until he can't walk or convulse or jiggle-dance or however he gets from place to place
Blake? Everyone is constantly slapping him and he still needs to be slapped, preferably while driving a Kia.
Paul? Needed to be slapped before he mocked Hayward, needs to be slapped twice now.
DeAndre? Needs to be slapped by Gobert.
Barnes? Came out of the womb and was slapped by his mother. Has been slapped by anyone seeing his face thereafter. Still deserves more.
The bench? If one existed, would need to be slapped.
