I'll probably just beat around the bush here and forgive me for that but, who are we to say what cultural Entity is worse, when all are known world wide, and when all are successful in their own right, but varying on what region it is?
American Football obviously being most popular in the states, better then Soccer, which at times was a dying force in the states, but a huge and I mean huge force world wide?
Just because we don't like a sport, we may hate it, but does that make it the worse sport because we think it is?
Now to answer the topic, my least favorite sport ( which will be my worse sport to y'all. ) would probably be Golf. Though I can easily respect it and can see why a lot of people like it... It just bores me.
And just to voice it, my favorite is Baseball or Soccer. I'm horrible at Baseball though because It is in my personal opinion the hardest sport to play skill wise, but I love watching it on Tv and in person when it isn't 100 degrees outside. Soccer being a sport I played when I was 7 till about my teen years, I just loved it.
Okay, civil rant over. =p
