I'm not a big fan of any of the mentioned organizations. Their original aims and intentions may have been laudable, and they may well retain good intentions, but money and power invariably seems to corrupt them in some way. None of them get my money. I simply haven't got enough to throw their way whether I like them or not.
I tend to think that none of them are especially anti-angling, with the possible exception of elements of the RSPCA and some small local groups populated by zealots. However, like large parts of the general population, I suspect that there's a low level principle of being anti-angling. I'm not talking about a anti-angling sentiment that would actually involve actually doing anything, simply an underlying "I'd be happy if angling ceased" kind of thing. It's much like my own anti-religion stance. I'll be happy to see the end of all religions. However, you won't find me doing anything whatsoever to bring that about.
However, I firmly believe that there are plenty of landowners that are utter hypocrites where angling is concerned. I've encountered more than one or two that aren't fans of angling, for all sorts of reasons. However, they are happy enough with the money it brings them. The problem is that when the financial benefits are outweighed by other factors, angling will be history on their land. That's one of angling's biggest problems, when old historical angling venues change hands and end up being controlled by owners that aren't as amenable to angling. That can simply be by the progression of local council members, a parent passing away and a son/daughter taking over, or a total change of ownership.
