Might well be, but this behavior is childish. Even my 3 year old nephew doesn't destroy the sandcastles of kids he envies any more.
It's about freedom of choice for me, about live and let live and what CMAS does to me personally, restricting my freedom, by acting the way it is.
Where I live CMAS is completely against competitive freediving of any form. A while ago, I wanted to start monofin swimming as addition to freediving and thus contacted a finswimming club. I wrote an e-mail and communication was fine - until the moment they seemingly found out that I am a freediver. Never heard from them again. I wrote several e-mails to several contact persons. They didn't even have the guts to tell me that they do not want to have anything to do with a freediver.
Stuff like that really makes me go
