A lot of people are narrow minded when it comes to the question of a PREFERENCE. People are getting so upset when they don't have the same preference. "OMG HOCKEY IS THE BEST, SOCCER SUX YOU SHOULD LIKE HOCKEY INSTEAD". It's fucking childish. I embrace when someone prefers a different sport, and then I will find out why, by either trying it out or watching it. And most of the time I actually quite enjoy it also.
Ahem, sorry about that I just needed to get that out. Another great sport that no one has mentioned is any sort of competitive fighting, whether it be Kickboxing, Boxing, Judo, Wrestling, or any sort of Mixed Martial Arts match, which is my close second place favourite sport.
