Not an angler myself but have been involved in it almost all my life and now work in a closely related field.
It's hugely dominated by men, as a pp said. I'd guess that 90 of those men would be in agreement with us.
The problem with the kind of man who's into fishing (across the board - coarse, shore, fly-fishing) is that, in common with much of the population, they are behind on this, it hasn't affected them. Unless they have a wife, daughter, sister, mother, or female colleague or fishing pal who has opened their eyes to this they just aren't aware of it. I'm often amazed at how little otherwise intelligent, interested men who care a great deal about other people, including women, know or even care about this.
A great thing about fishing is that taken as a whole (coarse, fly-fishing etc) it includes people (although mostly men) of all ages, across class divides and political divides. Just typing that I'm sure the same could be said of football, rugby and more.
I wonder if there's something to harness there - as previous poster said, there's freedom in not being attached to powerful sponsors.
