FunnyOnion Welcome to Mumsnet, or have you recently name changed? 
I think it's out of order someone with mobility issues thinks they have a right to these spaces tbh Wurts. Just as I would think it's disgusting anybody other than a disabled person would use a disabled space.
I think it's out of order for anybody who resents someone with a disability using a space that is safe and convenient for them, no matter what label it has been given.
Tbh if a disabled person had no choice but to use the parent space, fine I get that.
Why thanks for your generosity, Dds and I shall doff our caps next time we see you.
Both have parking areas and if there aren't enough then moan about the retail outlets and shops, not parents for daring to use an area that keeps their child safe and makes life easier.
It's not the people with disabilities complaining, we did campaign, talk to the retail stores etc. It's the parents complaining about those nasty people with disabilities daring to leave the house and use your spaces; ergo you talk to the stores.
Your complete fucking nonsense about compliance officers and benefit fraud being rife is exactly that: complete fucking nonsense. As is your complete nonsense about winning and being right or wrong. It's great that P&C spaces are there, but grow the fuck up, develop some empathy and if a person with disabilities needs that space for whatever reason accept it with good grace.
On a final note, disability benefit fraud is less than half a percent. 0.04%. That is not rife, annecdata does not trump data.
