I completely agree. Grappling is a fine sport. Sport. One of the best workouts ever. Remember it comes from jujitsu, along with the arts of Aikido, Judo and several Karate systems. To confuse sport with combat only results in uneccesary suffering for both parties. BUT, How many fights are you going to get into? Hopefully NONE.
Therefore the sport has a value and an outlet. However you will never see the best self defense systems on TV ;-)
