People with disabilities are the most maligned group in the UK. Starting in childhood where they are seen as inconveniences, to adulthood where workplaces, landlords and even the transport and public amenities present easily preventable difficulties.
Nobody complained when Yvette Cooper introduced punitive changes to DLA at the end of the 2000s, nor did they care when Cameron and Duncan Smith wielded the largest axe in public history. Theirs was a government that oversaw cuts to local transport funding for children with Downs Syndrome, ffs!!!! What makes you think the current shower will care this time around?
Disabled people need to realise the only way to improve their lot is to take a leaf out of the trans movement's book and start an equality movement. There is power in large numbers, and more power in getting aggressive. The civil rights movement in America was not successful off the back of inaction, those rights were hard fought and hard won.
There are roughly 13 million people in the UK with a disability (so 1 in 6). This number eclipses that of many other minorities from black and minority ethnic communities to the LGBT community. Even just 4 or 5 million people, along with 1-2 million carers and/or allies forming a network of pressure groups is a number too large for any government to comfortably ignore for long. Aggressive action is the only way forward.
