Funding would help with raised platforms by paying for the cost of "certificated and safe" ramps to allow you access which is something you were complaining about it may also allow a modification of the shooting position and other infrastructure to suit you more.
Groundworks,metalworking and even wooden structures cost money plus time and effort to complete plus "certification for safety" and in some cases may even involve planning permission....some shoots would simply close under the financial weight.
Again many grounds just cannot practically make themselves fully wheelchair accessible,not because they do not want to but because it would be physically impossible.
I do not need to borrow a chair to see the challenges involved,i have shot with a local lad who comes to our club who is confined to a chair he has a large wheeled trike style and gets everywhere ...barring platforms which would be impractical for a small club on a site where stand position is changed every shoot.
I think he sees it as a challenge,enjoys it immensely and has never been seen to complain...i guess because he doesn't think it is everybody elses fault that the world wasn't designed for him and is happy that people make there best effort for him.
So you are demanding that all shoots including greenfield sites should have full access,well that,s the Worlds,Beretta gone then and many other big shoots...i can think of one shoot that is registered its on a farm with massively steep slopes and no fixed shooting positions from shoot to shoot...should they be forced to close causing a loss of facilities to the whole shooting community.
And i will repeat i do not believe anyone is deliberately trying to exclude you though you obviously believe that everyone is.
So lets ban any shoots on greenfield sites,any shoots that are on uneven terrain,any shoots that don't suit you basically...nevermind that they may have been there years as small locally run enterprises and would make there best effort for you to enjoy your experience there even though they may not be "suitable",sporting shooting has become far more accessible than it was but still not good enough for you
The nature of sporting shooting in general is that it is in the countryside and the countryside is rough,uneven,hard to access...it seems your suggesting that everything should be shot from flat concrete pads with perfect access over permanent paths with no real variation in topography?
Might as well take up Trap shooting then? Never going to happen and i think i would probably give up shooting if sporting was forced to be the same.
People should make their best effort to accommodate you where practical and safety is not a concern.
You talk about legal action to enforce your will,guess we can kiss sporting shooting as we know it goodbye then if you get your way.
