Things I Hate About Badminton:
Some things that really bother me about badminton are those so-called "Gentlemen's" sport rules. Rules like no clothing with sayings, and no talking during the game. I should have the right to pick what I feel appropriate to wear. Most people think that the same things are appropriate.
Other rules such as no touching the net with the racquet are there just as a precaution and should be judged by a ref whether your distracting your opponent or not. The rule shouldn't just be made.
Speaking of refs, there aren't any, which means your opponant could be lieing about whether its out or in. I don't really like trusting people who will do anything to win. But, sometimes you could not know what to call it and are accused of cheating.
In general, don't go into badminton without knowing what your getting into. It usually causes a lot of frustration later.
