Kevin it is relevant inasmuch as it is a lunatic fringe that is involved, and the same is true to a lesser extent regarding fox hunting. As for fishing it is the largest participant sport in the UK, and the 'Game Fishing' section which is what I think you may be referring to when describing it as a posh pursuit is a mere fraction of those who partake of the sport. I don't think that many of the peolple you see lined up along canal banks, and round lakes at numbered pegs fishing in competions are alumni of Oxford or Cambridge universities. It is and always has been a predominantly working mans sport.
