Do you really think that because people cannot as easily (w/o prosecution) beat the crap out of someone for 'not belonging' is ruining surfing? Come on. The ocean is not real estate. It is not owned by anyone.
There are plenty of way to regulate a line up outside of using violence. First step is to speak up, and let the kook know about their infractions. If that does not work, positioning is key. If you have even three competent surfers working together, you can completely skunk another persons (or groups) session. If nothing else works, remove a carburetor and drop it in the water. jk. I've always thought the beat down was the least creative way to protect your wave. Sure, it is effective in many cases. And still wrong.
Claiming surf clubs as gangs is just silly (except for that one in Point Break), and I agree the easy out - instead of going after actual gangs. But stopping assault on the beach is a very good thing IMO.
I've always thought the surfing community dynamic was interesting. Surfing has always brought me a sense of solace. Engaging with a wave and being out in the ocean is special. I think most folks surf in order to enjoy themselves. Yet, add too many surfers (sometimes that is just one other person) to the mix, and things tend to become competitive. Waves are a limited resource. People tend to put the blinders on and become a bit more selfish. And then at some point, tempers flare, and people get pissed off. Then you need to begin to wonder what the entire point of being out is.
