Yes, but you are clearly not rooting for someone to win by KO, you are rooting for someone to lose by KO.
When I root for TJ Dillashaw to win, its because I know that in the process hes going to display some sweet footwork and set ups and well put together combinations.
You are not rooting for Amanda Nunes to KO Ronda because she has sick Floyd Mayweatheresque boxing skills and you want to see them displayed, you just want to see Ronda get KO'd/hurt because she is annoying.
That right there is the difference.
You just seem use fighting as a scapegoat because you enjoy seeing people get hurt.
