Uncle Jaffa has a set of varied positions on these sort of situations.
First off we do not know the back story. I have pushed people off waves I have punched the nose of a short board out, I have launched verbal tirades not through a sense of entitlement but because talking to the people who engendered these response virtually said FU and proceeded to continue dropping in.
Our break can be world class or a really good learners break. Often the better guys will leave the learners days alone and let them get on with learning.
The better days are now ( thanks internet) no longer a protected happy event , out of towners arrive in ever greater numbers and because they are passing through often have no manners towards any other surfer.
We have a crew of upcoming grommets and a good crew of excellent women surfing.
The local way is taking turns and sharing and mutual encouragement .
Visitors who join this format are welcome .
Newbies who venture out on the better days are told the traffic rule gently , if they are unheeding then they get pushed to the side more and more because of the danger they pose to both themselves and others.
The old hands have often been told to mind their own business in deleted expletives and then 20 minute later having to rescue the same person.
I have had aggressive short boarders aiming their board at my head when dropping in ( having previously called them into a
wave or two). He was the one I punched a hole through the nose of his board.
Rinky you are a civilised guy, what would your responses be under similar circumstances?
How would you assert a space for yourself in that sort of crowd?
99% of the time our break is mellow, we know who our misfits are and we can choose to be in the water with them or not.
We haven't got the Indonesian luxury of consistent surf seasons nor have we the crowds but 60 out on a classic day, hmmm, but the traffic knows its way around.
40 or so on a school holiday learners day that is good for just that, we protect the learners local and visiting from aggression and encourage sharing.
It is mainly the young "adults" and the fat, rediscover my youth, business men who ruin that sort of day.
Are there options to go elsewhere? Sometimes!
Unwritten rubber rules, truly !

I've taken up troll hunting just for fun, instead of a rifle I'll just use a pun! 冲浪爷爷
