So let's just summarise shall we?
Times have changed so riders should cheerfully abandon historic rights for pedestrians.
All riders are rich Tory bastards
Most riders can run a lorry/ trailer, and should share for free with the few who can't.
Riders all have the time and inclination to travel just for a short after work hack.
Everywhere has magical abundant trailer parking and limitless off road riding.
All horses can wear nappies. As evidenced by an unpleasant google image.
If some riders are inconsiderate and use pedestrian only spaces then it's best to tar all riders with the same brush.
All riders can mount lightly from the ground.
Everyone rides quiet plods they can safely hop on and off at any time.
Members of the public would never make it dangerous for a rider to be hopping about on foot kicking poo
It's a cracking idea to ride with a trowel, definitely no safety issues.
If wheelchair users have genuine difficulties in a shared space, it's the riders problem to solve it.
There definitely aren't any ill informed stupid class preconceptions about riders, we are all landed gentry.
Horse poo is harmful to humans and the same as dog muck
