Dunk, that's the point, I'm not suggesting that we all unify, or in fact that organisations don't already exist representing large numbers of anglers.
What I'm saying is that I don't think one vast alliance will ever be formed in the current climate, but notwithstanding that, if there was a call to ban our sport I think you would get the support of the 'silent' majority.
In answer to your question I have been an occasional angler for some years but only recently got really hooked, and I have not as yet joined any of the groups you listed, I did join the ACA out of my concern for pollution of our environment as soon as I became aware of the work which it undertakes. Through this forum I hope to discover more about angling and anglers, and I would not discount my joining any of the groups listed.
