What a load of utter arse. As usual.
People with disabilities serious enough to warrant a blue badge are always going to find day-to-day things much harder than those without disabilities. It is therefore appropriate, in a society that believes it should be inclusive, to find ways of making things easier for them.
Free parking makes normal daily tasks more do-able for many disabled people so free parking is a good thing. If a particular individual finds it patronising or unecessary then I am sure that person can live with it better than a dozen other people could live with being unable to afford to do their grocery shopping or go for a cup of coffee with a friend. You know. Just as if they were just like other "normal" people, rather than being the slightly less-entitled sub-species that they clearly should accept that they are.
The existance of free disabled parking does not affect any non-disabled person at all. If disabled people have to pay for their parking, the Council are hardly likely to think "ooh, what shall we do with the extra money? I know, let's reduce everyone else's parking charges."
Maybe, just maybe, everyone who doesn't need this "perk" could try to just be pleased for those who do that it is available in some places. And perhaps sympathise a little when it isn't.
And RVF400 re: "(Where can I get one?!)"
That is easy. Chop one of your legs off or contract a life-limiting illness. I am sure a blue badge will more than compensate for the downsides of your resulting disability.
