Yeah, we don't have a healthy attitude to disability as a society and the right-wing have deliberately set out to make that worse in order to justify targeting us for the worst of the austerity cuts. I've not yet had anyone collide with my wheelchair, which is still so new ' my wheelchair' sounds strange, but I've had plenty of people try to walk through me while I'm on crutches. I usually try to arrange it so they come off worst :)
